I have volumes of deleted files archived to dvd. I did a test between 2 of
my systems. The first command is ran against my file set on an ext4
filesystem. The second command is ran against my file set on a reiserfs on
an nfs mounted server. That server is using reiserfs for it's volume.
Before one thinks this is an NFS problem, I did the test from the NFS server
and the results are the same and using the same version. I saw this same
thing years ago when mkisofs was the around and I may have reported the same
bug back then. It was never fixed from what I can tell.
