sid: USB-stick - /dev/disk/by-id/ not populated

[Bruno Voigt <Bruno.Voigt@ic3s.de>]

Hi all,

I have one daily updated sid system running,
which doesn't populate the /dev/disk/by-id/ path
for an connecting USB-stick (w32 FAT)
as it is done by my other sid systems.
(it only shows up as eg /dev/uba1)

I compared the /etc/udev/rules.d/ contents
and they look very similar,
e.g. persistent.rules is identical.

Which rule/file is responsible
for populating the /dev/disk/by-id/ path.

How can I debug what's going on?
I suspect it might be some left over cfg
from older udev-releases or so,
because the system is very old / always being upgraded from sarge/or older.

TIA for any hints,
Bruno
