[Buildroot] [PATCH 0/3 v2] udev providers: compile the hwdb at build time (branch yem/host-eudev-2)

[Yann E. MORIN]

Hello All!

The *.hwdb files installed by eudev or systemd are "source" files; they
need to be compiled into a binary form to be useful.

This needs udevadm to be available, so we introduce a eudev host variant
to provide it, and use that from both eudev and systemd to compile the
database during target-finalize.

---
Changes v1 -> v2:
  - do a custom configure and install of host-eudev, to simplify the
    hooks  (Carlos)

Yann E. MORIN.

[Buildroot] [PATCH 1/3 v2] package/eudev: introduce a host variant

[Yann E. MORIN]

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, an 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.

We don't actually need this, since /etc/udev/udevdb.bin is a valid
location for systemd too. It was my idea, but I take it back. :-)

Are you sure that works? The sysconfdir is used both for the input and
output location. If you use systemd then the files provided by
systemd-udev presumably gets installed under /usr/lib/udev/hwdb.d as
well?
