Hi Christian,


On second thought...

I had a bad night tonight and was thinking a long time about this and
that.  It suddenly occured to me that there might be another problem
with this approach, attaching ordinals to the label name.

Assuming you have a single filesystem labled "VOLUME" which is on a
fixed disk.  So you get something like this:

  $ ls -l /dev/disk/by-label
  total 0
  lrwxrwxrwx 1 corinna vinschen 0 Nov 22 10:09  VOLUME -> ../../sdb1
  lrwxrwxrwx 1 corinna vinschen 0 Nov 22 10:10  root -> ../../sda3

Now you insert an USB Stick with a FAT32 filesystem, also labeled
"VOLUME".  Now you get something like this:

  $ ls -l /dev/disk/by-label
  total 0
  lrwxrwxrwx 1 corinna vinschen 0 Nov 22 10:12 'VOLUME#0' -> ../../sdb1
  lrwxrwxrwx 1 corinna vinschen 0 Nov 22 10:12 'VOLUME#1' -> ../../sdc1
  lrwxrwxrwx 1 corinna vinschen 0 Nov 22 10:10  root -> ../../sda3

So the label name changes, depending on inserting or removing another
partition.

Not saying I have a good solution myself, so I wonder if we should just
let it slip, but I thought we should at least talk about it...


Thanks,
Corinna
