Description of problem:
When using genisoimage to create a Rock Ridge + Joliet session with -r -J, the
Rock Ridge directory "/.."  is included. When merging a subsequent session with
-r -J -C MMM,NNN -M /dev/cdrom, it fails because "/.." and (e.g.) "tmpdir/.."
have the same Rock Ridge name.

mkisofs for fc6 did not have this problem, but in that case the -M 2,0,0 faux
scsi notation was used. It is possible the use of -M /dev/cdrom (required for
Fedora 7 libata) provokes this new behaviour (inclusion of "..").

I think this problem is distinct from
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=248262
(bad Joliet).

Version-Release number of selected component (if applicable):
genisoimage-1.1.6

Steps to Reproduce:
1. Create Rock Ridge session
2. Write to multisession CD
3. Create second session for CD
  
Actual results:
Error with duplicate Rock Ridge names.

Expected results:
genisoimage fails with duplicate Rock Ridge names.

Additional info:
Workaround is to roll back to genisoimage-1.1.2-4.fc7.x86_64 (from Fedora
release). This version reports that (e.g.) "tmpdir/.." is ignored when creating
the image.

Given this bug and
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=248262 ,
is it time for a genisoimage-1.1.6 product recall?

yum.conf exclude=genisoimage is your friend.
