Bug#845442: udev: does not honor configuration files in /etc/udev/hwdb.d

[Norbert Preining]

Hi Michael, hi Martin,

Well, not exactly. It reads that one can add arbitrary files and they
are loaded in the numerical order, where files named the same way
the /etc version takes precedence.

That means, in principle, adding
	/etc/udev/hwdb.d/61-local.hwdb
with only my entries should work, right.

And indeed, using systemd-hwdb query I *do* get the correct results:

$ pwd
/etc/udev/hwdb.d
$ ls
61-local.hwdb
$ cat 61-local.hwdb
evdev:input:b0003v045Ep00DB*
 KEYBOARD_KEY_c022d=pageup
 KEYBOARD_KEY_c022e=pagedown

$ udevadm hwdb --update
$ 

And now:
$ systemd-hwdb query evdev:input:b0003v045Ep00DB
KEYBOARD_KEY_c022d=pageup
KEYBOARD_KEY_c022e=pagedown
$

which is correct. But this was the very setup I had in the very beginning, 
so it seems that either the initramfs is not constructed correctly, or the
udev in the initramfs works differently.
Or something else I don't undestand - like most of systemd.

All the best

Norbert
