package/util-linux: build programs and libraries in separate packages
The different tools and libraries in util-linux have a lot of optional
dependencies. When we want to support those optional dependencies, we
can easily generate dependency cycles. For instance, findmount and lsblk
need udev to work correctly, but eudev and systemd both depend libblkid,
which comes from util-linux.
Normal distros (e.g. Debian) solve this by first building a minimal
package that has no dependencies at all, then build the packages that
depend on util-linux, and finally rebuild util-linux with all bells and
whistles. Solve it in Buildroot by means of the following changes:
- Split util-linux into two packages:
- util-linux-libs, providing lib{blkid,fdisk,mount,smartcols,uuid}.
- util-linux, providing both the aforementioned libs and the programs.
- Add a blind selection for util-linux-libs, i.e. it is indirectly
selected according to the util-linux options.
- Make host and target util-linux have a build dependencies on the -libs
packages.
- Make eudev and systemd have build dependencies on util-linux-libs.
This can be extended to other packages in the future but is not needed
right now because the configuration options are backward-compatible.
- Make util-linux have an optional build dependency on the package that
provides libudev (either eudev or systemd), if it is selected.
Installing util-linux overrides files installed by util-linux-libs but
this is not a problem: it's allowed for a package to overwrite files
from another package, as long as there is a dependency between the two.
util-linux-libs has a Config.in symbol for the package as a whole, but
not for the individual libraries: it simply reuses the symbols of the
full package.
The build dependency of util-linux on util-linux-libs ensures that
util-linux overwrites the files installed by util-linux-libs and not
vice versa. In practice this dependency shouldn't be needed: the only
reason for util-linux-libs to be built is to break a circular
dependency. In that case, there is already a transitive dependency of
util-linux on util-linux-libs, so adding it explicitly is redundant.
Still, better safe than sorry.
host-util-linux-libs is not needed at the moment. It can be added if we
have a dependency cycle problem later.
With this approach we don't need to patch configuration files neither
change packages other than eudev and systemd.
Other packages that require util-linux libraries and whose libraries may
be used by util-linux programs can be updated later. We also don't need
to change any existing defconfig, since all configuration options are
kept in the util-linux package.

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.

package/eudev: introduce a host variant
eudev and systemd provide a hardware database (hwdb) as a set of
multiple files. Various other utilities may also use that database.
Those files have to be "compiled" into a binary to be useful; libudev
(and thus all utilities based on it) only use the compiled hwdb.
Compiling the hwdb is done with udevadm, using the hwdb sub-command:
udevadm hwdb --update
Provide a simple host-variant of eudev, so that we can call udevadm at
build time.
When it is configured, eudev will shoehorn its --prefix path as the base
location where the .hwdb file will be searched from, as well as where
the hwdb.bin will be generated in. This means that with the usual
--prefix=$(HOST_DIR), it would look into there.
udevadm also accepts a --root=/path option at runtime, which prepends
/path to all the paths it uses to find and generate files.
Obviously, combining --root=$(TARGET_DIR) and --prefix=$(HOST_DIR) would
not do what we want: all files would be searched for, and generated, in
$(HOST_DIR)$(TARGET_DIR)/ . Avoiding use of --root would not help much
either, as files would still searched in $(HOST_DIR) (we could use a
trick to copy files there, generate and then move the hwdb.bin, but
that's not nice).
However, since we only need udevadm, and since udevadm has no internal
and no external dependency, we can use a less dirty trick and configure
host-eudev with --prefix=/usr (and similar for the other paths), manually
copy udevadm to HOST_DIR, and then use --root when calling it.
Then, we get a udevadm that can read files from, and generate files into
$(TARGET_DIR). We register a target-finalize hook to generate the
hwdb.bin, so that any pakage may install its .hwdb files (currently only
eudev and systemd do, but other packages might (e.g. sane is known to do
so on standard desktop distros))
The *.hwdb source files consume a lot of space, roughly the same as the
generated database, i.e. ~8MiB as of today, and they are totally useless
on the target; only the generated hwdb.bin is useful. So we want to get
rid of them.
However, we also want to be able to complete a build (e.g. make
foo-reinstall to reinstall more hwdb files), so we don't want to
irremediably lose them. As such, we register a pre-rootfs-cmd hook, that
removes them just before assembling the filesystems, when we're only
using a copy of the target directory.
Note that this is the first host package to register a target-finalize
hook, and also the first to register a pre-rootfs-cmd hook. This avoids
duplicating these hooks logic in both eudev and systemd.
