Comment 23 for bug 102097

Sadly, I've still got the problem.

I know *where* the problem is in my case, but no idea how to fix it :-(
(See https://bugs.launchpad.net/ubuntu/+source/udev/+bug/118292)

It comes down to vol_id not recognising a vfat partition: the device entry is created, and I can mount it by hand:
$ sudo mount -o ro -t vfat /dev/sdg1 /mnt
works fine.

But, /sbin/vol_id shows:
$ vol_id /dev/sdg1
/dev/sdg1: unknown volume type

Of course, the system *can* recognise the partition properly if you use a different command:
$ blkid /dev/sdg1
/dev/sdg1: LABEL="SEA_DISK" UUID="0000-0ED4" TYPE="vfat"

So as 118292 says, it's a udev (vol_id) bug (possibly under Ubuntu).

I am somewhat loath to do the workarounds suggested (especially rewriting vol_id as a shell script), but unless somebody decides to fix it "properly", I don't see much choice.
I've been living with this bug since Feisty broke Edgy, and Gutsy is no better (yet :-), but it's a bit of a pain...
