Currently, when one does not enable remounting the rootfs read-write,
i.e. keep it read-only, for example because the filesystem is actually
read-only by design, like squashfs, then two things happen:
- we create a factory from the content of /var at build time, register
tmpfiles entries for it, and mount a tmpfs on /var at runtime, so
that systemd-tmpfiles does populate /var from the factory; this is
only done when the rootfs is not remounted r/w;
- we trigger systemd-tmpfiles at build time, which uses the tmpfiles
db, of which our /var entries, to pre-populate the filesystem; this
is always done, whether the rootfs is remounted r/w or not.
Note that Buildroot mounts a tmpfs on /var, and leaves to the integrator
to care for providing an actual filesystem, as there are too many
variants and is very specific to each use-case.
These two mechanisms are conflicting, semantically, but also
technically: the files from the factory will be duplicated, but that
may help in some situations when the actual /var filesystem is not
mountable.
In some cases, it might be preferable to have none, either, or both
mechanisms enabled; it highly depends on the ultimate integration scheme
chosen for a device.
For example, some people will be very happy with a /var that is actually
on a tmpfs and that it gets reseeded form scratch at every boot, while
others may want to ensure that their system continue to work even when
they can't mount something that makes /var writable.
YMMV, as they used to say back in the day...
So, we introduce two new options, in the system sub-menu, each to drive
each mechanism. We default those options to y, to keep the previous
behaviour by default, except the var factory is only available when the
rootfs is not remounted r/w, as it were so far.
We still hint in the help text that there might be some conflict between
the two mechanisms, but since it has been that way for some time, it
does not look too broken for most people.
Since that introduces more options related to systemd being chosen as an
init system, we gather those two options and the existing one inside a
if-endif block, rather than adding more 'depends on' on each options.

Some externals may wish to provide custom init systems for tightly

however a downside to the BR2_INIT_NONE is it forces the custom init

each target, or skeleton-init-none which isn't a complete skeleton.
Allowing br2-external to define custom BR2_INIT_* means they can now

Currently, the dependencies for the init system choice, and the

same order, the latter making it difficult to assess consistency between
the two.
Fix all that, by cross-duplicating dependencies from the init choice and
the package, and order the dependencies according to the manual (arch
first, toolchain, then the others).
Note that some dependencies are redundant, but kept nonetheless for
correctness:
- BR2_USE_MMU is implied by BR2_TOOLCHAIN_USES_GLIBC, but systemd does
use fork();
- !BR2_STATIC_LIBS is also implied by BR2_TOOLCHAIN_USES_GLIBC, but it
is also inherited from kmod which we select;
- BR2_TOOLCHAIN_HAS_THREADS is also implied by BR2_TOOLCHAIN_USES_GLIBC,
but systemd does use pthread_*() functions.

We install a template getty service, and we 'instantiate' it in the
default runlevel, using the configured tty.
Ideally, packages that provide a getty program would be responsible
for installing the corresponding service file. However, to keep
consistency with the existing init systems (busybox, systemd, and
sysv), so we do provide it from the openrc package itself.
OpenRC only acts on the files in a runlevel sub-directory, but the
documentation [0] actually suggests that the instance symlink be done
in init.d, and then again symlinked into the actual runlevel
sub-directory. So, we abide by the rules.
Also, to be noted, the getty service file is installed without ensuring
that a getty command is available. This again is not unlike other init
systems, sysvinit and busybox, which behave the same.

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.

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

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.

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

/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

Allow automatic network configuration via systemd-networkd if selected.
If systemd-networkd is enabled and $BR2_SYSTEM_DHCP is set, then create
a .network file to configure the selected network interface via DHCP.

[Thomas:
- merge the two patches from Eric into just one
- instead of generating the dhcp.network file completely from the .mk
file, use a template file, and "sed" it with the right network
interface]

Commit 006a328ad6 ("util-linux: fix build with ncurses") removed
dependency on BR2_USE_WCHAR, but failed to update the reverse
dependencies of util-linux.
This commit updates comments in Config.in for BR2_USE_WCHAR for reverse
dependencies of util-linux which directly uses wchar now or when it is
pulled from other dependencies.
eudev doesn't use wchar directly, but needs C99 compiler. Autotools
generate code with wchar_t for checking C99 compiler.

Currently, we limit installing zoneinfo to non-musl toolchain, by lack
of knowledge on how it would work on musl.
Turns out that musl uses the same zoneinfo format as glibc does.
Make it possible to install the TZ info whatever the C library; for
musl, use tzdata as for glibc.
Thanks Rich! ;-)

The options to purge locales and to generate locale data are currently
located in the toolchain menu. However, these options are not really
related to the toolchain per-se, they are more system-level
configuration options, much like the timezone selection option we
already have in the "System configuration" menu.
Therefore, it makes more sense to have the locale-related options in
the "System configuration" menu as well.

We expect the custom skeleton to be fully filled with the necessary
files, now. There is definitely no reason we should handle setting the
hostname and the issue file in there. A user using a custom skeleton
should be fully responsible for providing a functional skeleton.

In the following commits, we'll be switching more options to be
conditional on the default or custom skeleton.
So, it makes sense that those options come after the choice of a
skeleton.

Being custom means that our default one is not suitable to start with.
So there is no reason to offer it as the default path.
Add a check that it is not empty.
Add a separating empty line, for good measure, too.
