Package: udev
Version: 0.100-2
Severity: normal
As you can see from the attached z25_persistent-cd.rules, the same
external USB CD ROM gets assigned different names depending on where
it is plugged in.
In general, this is not a bug (for example, if I plug in several CD
drives, I understand that they may be numbered differently depending
on how I install them).
In this particular case, I assert that it is a bug, because it was the
same CD drive plugged in to two different USB host adapters, but in
each case it was the only CD drive plugged into my system, so it seems
reasonable that it should be /dev/cdrom, so that many common programs
that default to this device name will find it.
Put another way, it seems odd that on a system with only one CD drive,
it should end up as /dev/cdrom1, and not /dev/cdrom.
Finally, I note that in my z25_persistent_cd.rules file, there are two
rules for the same drive which correctly give it the same name (but I
think these were generated together, as one seems to be a special case
of the other), and one which gives it a different name.
Sorry for my cluelessness regarding USB and udev, but I have read the
several other bug reports in this area carefully, and my bug seems to
be different from all of them (in particular, I am running udev
0.100-2, which seems to fix earlier similar bugs).
