OK, I have some new experiences. The symptom is related to the fact that hald
cannot create an appropriate entry describing the volume (/dev/sdb1 on the USB
stick).

Instead of an entry such as /org/freedesktop/Hal/devices/volume_uuid_45E7_069B
it can only create on like
/org/freedesktop/Hal/devices/volume_part1_size_2062058496.


And this is related to that udev cannot create a symlink to /dev/sdb1 in
/dev/disk/by-uuid

And this is because /sbin/blkid -o udev -p /dev/sdb1 recognizes the volume as a
raid member instead of a standalone volume bearing a filesystem:

milleniumfalcon:~ # /sbin/blkid -o udev -p /dev/sdb1
ID_FS_VERSION=74.74
ID_FS_TYPE=jmicron_raid_member
ID_FS_USAGE=raid

Running /sbin/blkid -u filesystem -o udev -p /dev/sdb1 leads to an accpteble
result:

milleniumfalcon:~ # /sbin/blkid -u filesystem -o udev -p /dev/sdb1
ID_FS_LABEL=BackTrack3
ID_FS_LABEL_ENC=BackTrack3
ID_FS_UUID=4912-D6CF
ID_FS_UUID_ENC=4912-D6CF
ID_FS_VERSION=FAT32
ID_FS_TYPE=vfat
ID_FS_USAGE=filesystem



And in fact, the problem can be eliminated by modifying
/lib/udev/rules.d/60-persistent-storage.rules:

# probe filesystem metadata of disks
KERNEL!="sr*", IMPORT{program}="/sbin/blkid -u noraid -o udev -p $tempnode"

instead of

# probe filesystem metadata of disks
KERNEL!="sr*", IMPORT{program}="/sbin/blkid -o udev -p $tempnode"

Solves my problem. I don't know anything about udev/hal/dbus, but I think "-u
noraid" MUST NOT be applied to openSUSE 11.2.



So, the problem's root is that when I instaled backtrack 3, some garbage was
applied to the volume which causes blkid to misdetect the type of the volume.
Like for this guy: http://www.spinics.net/lists/util-linux-ng/msg02530.html

Can you reproduce it by installing BackTrack 3 to an USB stick with a FAT32
filesystem?
