Watch out for keymap breakage with latest saucy udev

Hello all,

Some weeks ago, current udev upstream versions switched from the old
/lib/udev/keymaps/ and 95-keymap.rules+95-keyboard-force-release.rules
to using hwdb (/lib/udev/hwdb.d/60-keyboard.hwdb), which is much
faster, avoids tons of little files, and is much simpler to maintain.
As before, users/admins can still override/test local changes in
/etc/udev/hwdb.d/.

Quite a number of keymap updates happened since then and more will
follow, so I think it's better if we jump to the hwdb schema now even
though we can't currently upgrade to the current upstream release.

So I just uploaded a new systemd 204-0ubuntu10 with the keymap hwdb
stuff backported, so that from now on pulling current keymaps from
upstream is trivial. I tested this on my ThinkPad X201 and it works
fine there, but in theory it might happen that there are regressions
on some models.

So please upgrade to udev 204-0ubuntu10, reboot, and check that your
Fn magic keys still work as expected. If not, please file a bug
against systemd (with apport, please).

Thanks,

Martin
