8bbb040e1e skeleton: Rename skeleton-sysv to skeleton-init-sysv
The skeletons are based on the selection of BR2_INIT_*, so add init- to
the package name to make this clearer. While skeleton-sysv is relatively
clear, skeleton-common and skeleton-none are less clear on their
relationship to BR2_INIT_*. So rename skeleton-sysv to conform to a
clearer pattern.

26085bbbd5 system: make systemd work on a read-only rootfs
When the rootfs is readonly, systemd will expect /var to be writable.
Because we do not really have a R/W filesystem to mount on /var, we make
it a tmpfs [*], and use the systemd-tmpfiles feature to populate it with
"factory" defaults.

We obtain those factory defaults by redirecting /var to that location at
build time, using a symlink /var -> /usr/share/factory which is the
location in which systemd-tmpfiles will look for when instructed to
"recursively copy" a directory.

With a line like:

    C /var/something - - - -

it will look for /usr/share/factory/something and copy it (recursively
if it is a directory) to /var/something, but only if it does not already
exist there.

We also mark this copy with the exclamation mark, as it is only safe to
copy on boot, not when changing targets.

To be noted: the real format for such lines are:

    C /var/something - - - - /from/where/to/copy/something

But if the source is not given, then it is implicitly taken from
/usr/share/factory (which in our case is as-good a location as whatever
else, so we use it, and thus we need not specify the source of the
copy).

Note that we treat symlinks a little bit specially, by creating symlinks
to the factory defaults rather than copying them.

Finally, /var at build time is a symlink, but at runtime, it must be a
directory (so we can mount the tmpfs over there). We can't change that
as a target-finalize hook, because:

  - some packages may want to set ownership and/or access rights on
    files or directories in /var, and that only happens while assembling
    the filesystem images; changing /var from a symlink to a (then
    empty) directory would break this;

  - /var would be a directory on sub-sequent builds (until the next
    "make clean").

Instead, we use the newly-introduce pre- and post-rootfs command hooks,
to turn /var into a directory before assembling the image, and back to a
symlink after assembling the image.

[*] People who want the factory-defaults only on first boot will have
    to tweak the fstab to mount something else than a tmpfs on /var.

c0fd0ac655 package/skeleton: introduce sysv, systemd and none specific skeletons
Currently, we use the same skeleton for sysv-like init systems and
systemd, even though systemd has some peculiarities that makes our
default skeleton unfit.

So, we'll need to provide different skeletons (really, only part of
it) for sysv-like and systemd. In addition, in order to support the
"no init system" (BR2_INIT_NONE) use case, we introduce a "none"
skeleton.

Introduce three new skeleton packages, aptly named skeleton-sysv,
skeleton-systemd and skeleton-none. All three are providers of the
skeleton virtual package, in lieu of the skeleton-common package,
which is now a simple dependency of all three new skeletons.

Those packages are empty for now. In followup changes:
  - sysv-specific stuff will be moved out of skeleton-common and into
    skeleton-sysv;
  - systemd-specific stuff will be added to skeleton-systemd.

120307520f package/skeleton: split out into skeleton-common
Move all the handling of the default skeleton into a new package,
skeleton-common.

We don't name it skeleton-default, because it will be further split
later, into a skeleton for sysv and another for systemd, with some parts
still common between the two. So just name it skeleton-common right now;
this will save us a rename later.

While we're at it, also assign to SKELETON_COMMON_TARGET_FINALIZE_HOOKS
instead of directly to the global FINALIZE_HOOKS. Therefore, we don't
need to do all of that in a condition BR2_PACKAGE_SKELETON_COMMON==y.

Note: it would be technically sound to move the skeleton files together
within a sub-directory of the skeleton-common package. However, we refer
the user to those files, from various locations (manual, packages). It
will indeed be easier for the user to find those files in
system/skeleton/ rather than in package/skeleton-common/skeleton/

0c750a027b package/skeleton: split out into skeleton-custom
For the custom skeleton, we practicaly do nothing, except ensure it
contains the basic, required directories, and that those are properly
setup wrt. merged /usr.

Furthermore, our current skeleton is not fit for systemd, and we'll
have to split things out into various skeletons.

So, off-load the custom skeleton into its own package.

Thus, the existing skeleton package is now limited to:

  - when using our default skeleton, install and tweak it properly;

  - when using a custom skeleton, do nothing except for depending on
    the skeleton-custom package.

10ac06496c package/skeleton: select it rather than default to y
Our current skeleton is tailored to sysv-like init systems; it is not
fit for systemd-based systems. So, in upcoming changes, we'll add
another skeleton for systemd.

This means we can no longer have the current skeleton default to 'y', or
it would be enabled also for systemd, which would be incorrect.

So, we remove the default to 'y' but have it selected by the default
skeleton choice.

However, we do not yet have a way to directly build (really, install)
the custom skeleton, it is built (really, installed) as a dependency of
the default skeleton. So we must also forcibly select the default
skeleton when using a custom one.

Until we have the means to do only one or the other; i.e. when we have a
virtual skeleton.

7c1692df6f package/skeleton: drop dependency on host-mkpasswd
Setting the root pasword is done in a target-finalize hook, so we do not
need to enforce a dependency from the skeleton onto host-mkpasswd.

Dropping that dependency will simplify making skeleton a virtual
package (in up-coming changes).

Instead, it is now selected as any other package. As such, it is
guaranteed to be built before target-finalize.

This however introduces a slight change in behaviour: previously,
host-mkpasswd would only be built if we needed to hash the root password
from its plain-text value. Now, host-mkpasswd is always built as soon as
the root password is non-empty, even if already pre-hashed.

Since host-mkpasswd is a really tiny weeny package bundled in Buildroot,
with only two C files, built as a single unit with a single gcc call,
the overhead is really minimal. Compared to the simplifications this
will allow in the skeleton packages (plural: common, sysv, systemd,
custom) to come, this overhead is acceptable.

Yet another simplification, even if small, to ease providing multiple
skeletons.

dc057d2865 system: introduce BR2_SYSTEM_ENABLE_NLS
Until now, the option BR2_ENABLE_LOCALE was more-or-less controlling
whether NLS support was enabled in packages. More precisely, if
BR2_ENABLE_LOCALE=y, we were not doing anything (so some packages
could have NLS support enabled, some not). And only when
BR2_ENABLE_LOCALE was disabled we were explicitly passing
--disable-nls to packages.

This doesn't make much sense, and there is no reason to tie NLS
support to locale support. You may want locale support, but not
necessarily NLS support. Therefore, this commit introduces
BR2_SYSTEM_ENABLE_NLS, which allows to enable/disable NLS support
globally. When this option is enabled, we pass --enable-nls to
packages, otherwise we pass --disable-nls.

In addition, when this option is enabled and the C library doesn't
provide a full-blown implementation of gettext, we select the gettext
package, which will provide the full blown implementation.

It is worth mentioning that this commit has a visible impact for users:

 - Prior to this commit, as soon as BR2_ENABLE_LOCALE=y, packages
   *could* provide NLS support. It was up to each package to decide
   whether they wanted to provide NLS support or not (we were not
   passing --enable-nls nor --disable-nls).

 - After this commit, it's BR2_SYSTEM_ENABLE_NLS that controls whether
   NLS is enabled or disabled, and this option is disabled by default.

Bottom line: with the default of BR2_SYSTEM_ENABLE_NLS disabled, some
packages may lose NLS support that they used to provide. But we
believe it's a reasonable default behavior for Buildroot, where
generally NLS support is not necessary.

e7e526e910 system: require a timezone to be set
Even though no timezone implicitly means UTC, systemd is not all that
happy when it does not have a timezone set. This is all fine on a RW
filesystem because systemd will create a symlink on its own (to
Etc/UTC), but not so much on a RO filesystem, causing all kind of
issues at boot time (up to the point that the system is unusable).

We fix that by requiring that the timezone is actually set. The check is
done by verifying that the timezone file is an actual file; if not set,
the test would find a directory and would thus fail.

Update the help entry accordingly.

Also fix indentation in tzdata.

fc91501e6b system: do not overwrite /bin/sh Busybox symlink
The BR2_SYSTEM_BIN_SH hidden option defines to what binary the /bin/sh
symlinks should point to. If busybox is chosen, then /bin/sh is created
to point to /bin/busybox.

This works fine with the default installation mode of Busybox, but it
fails with the upcoming "individual binaries" mode, in which each applet
is installed as its own binary, and /bin/busybox doesn't exist: we get
/bin/sh as a broken symlink to /bin/busybox.

Since Busybox already installs its own /bin/sh symlink, properly
pointing to /bin/ash or /bin/hush depending on the selected shell, it
doesn't make sense for the BR2_SYSTEM_BIN_SH logic to override
this. Just let Busybox install its own /bin/sh by making
BR2_SYSTEM_BIN_SH empty when Busybox shell is selected as /bin/sh.

29206817d0 system: Fix warning when selecting systemd and ensure merged /usr workarounds are enabled
With systemd and a custom skeleton, we end up with the following warning:

warning: (BR2_INIT_SYSTEMD) selects BR2_ROOTFS_MERGED_USR which has
unmet direct dependencies (BR2_ROOTFS_SKELETON_DEFAULT)

Which makes sense as the logic to install the symlinks to /usr is part of
the default skeleton handling, but the BR2_ROOTFS_MERGED_USR symbol is ALSO
used by packages to activate various workarounds for a merged /usr, so it
should be always active when using systemd even with a custom rootfs
skeleton (that by definition must use a merged /usr as required by systemd).

So introduce a dummy symbol with the same name for the custom skeleton case,
similar to how we handle the BR2_PACKAGE_BUSYBOX_SHOW_OTHERS option.

This is a hidden option so it can only be activated by enabling systemd (and
not if people just want to use a merged /usr with a custom skeleton but not
systemd), but as this is really a legacy option that is probably good enough
(if not, patches are welcome!).

c5bd8af65e system: add options for /bin /sbin and /lib to be symlinks into /usr
systemd is increasingly expecting things to live in /usr/bin, /usr/sbin
or /usr/lib nad not in /bin, /sbin or /lib. It has inherited those
expectations from a Fedora change:
    https://fedoraproject.org/wiki/Features/UsrMove

Note however, that systemd does support /usr being on a separate
filesystem; it just expects an initramfs to mount it before the final
switchroot over to the actual rootfs.

But the traditional use-case for Buildroot is not to boot with an
initramfs; although that is totally feasible, that's probably not what
is commonly done in the vast majority of cases.

However, a lot of packages still install stuff directly into /bin,
/sbin or /lib, which systemd may need early-on in the boot process,
even before it may have a chance to mount /usr. Even though we can
tell systemd, at configure-time, where it should expect programs to
be at runtime, it does not make sense to go head-first against an
upstream wa^Hill.

Add an option so that /bin, /sbin and /lib be symlinks to /usr/bin
and /usr/sbin. That option is forcibly enabled when the init system
is systemd.

Note: we need not handle /lib32 or /lib64, as they already are symlinks
to /lib, which means they will automatically be redirected to /usr/lib,
as /usr/lib32 and /usr/lib64 already are.

Furthermore, this means we're no longer supporting a split-usr setup, so
the corresponding configure options have been removed as well for
systemd and, when using a merged /usr, for eudev as well.

In Buildroot, we decided (with this patch) not to support a split-usr
when systemd is used as an init system. This is a design decision, not
a systemd issue. Thus the select is with BR2_INIT_SYSTEMD rather than
with BR2_PACKAGE_SYSTEMD.

The "Dynamic using mdev" and "Dynamic using eudev" /dev management
methods are using devtmpfs, just like "Dynamic using devtmpfs only",
on top of which they add either mdev or eudev. But their names might
suggest they use mdev only or eudev only.

Clarify their descriptions by adding "devtmpfs +" to make it
unambiguous.

18fa4a32a6 system: allow/disallow root login, accept encoded passwords
Currently, there are only two possibilities regarding the root account:
  - it is enabled with no password (the default)
  - it is enabled, using a clear-text, user-provided password

This is deemed insufficient in many cases, especially when the .config
file has to be published (e.g. for the GPL compliance, or any other
reason.).

Fix that in two ways:

  - add a boolean option that allows/disallows root login altogether,
    which defaults to 'y' to keep backward compatibility;

  - accept already-encoded passwords, which we recognise as starting
    with either of $1$, $5$ or $6$ (resp. for md5, sha256 or sha512).

e26ec6e45c system: make /bin/sh symlink use relative path
The symlink created by buildroot for /bin/sh is the full path to
a shell.  This does not match what busybox and other Linux
distributions do with using relative path symlinks. When handling
files on the host system this will point to the host system's shell
if present and not the target shell.

This is fixed by changing the /bin/sh symlink to use a relative path.

Fixes #8161.

029179615e system: remove DES password encoding
DES is long dead, it is insecure as hell, and virtually all known
crypt(3) implementations now all support at least md5.

Besides, the character-space of DES-encoded passwords are a sub-set
of the character-space for a clear-text password, so we can't easily
differentiate between the two. Since we're going to change the root
password prompt to support setting encoded passwords (as well as
clear-text passwords), we can't keep DES or we'd be unable to decide
whether we'd need to encode the password or not.

Remove DES encoding altogether (and add a legacy entry). The default is
still md5, and thus there's no backward-compatibility 'select' to add.

131300e6f1 system: run getty on boot console by default
We used to specify explicitly serial port with all its settings
for init to instantiate getty.

This limits usecases when the same one rootfs could be used.

For example following cases won't work well with hardcoded
serial console settings:
 * On the same board other serial port is expected to be used
 * The same rootfs is intended to be used on different boards with
   different serial ports (like ttySx vs ttyAMAx or even ttyx)

With this change by default we rely on "console" specified in
kernel's boot command line.

What is important getty will be set on the last console
specified in bootargs.

For example is a kernel comand line:
--->---
bootargs="... console=tty0 console=ttyS3,115200n8..."
--->---

This now will instantiate serial console on ttyS3 but not on tty0.

Tested with both Busybox and SysV init.
