[vox-tech] iso9660 question

[Peter Jay Salzman]

is there a way of learning which extensions are being used on a mounted
cdrom?

i'd like to burn a copy of suse 7.0.  since the cd is bootable, do i need
to use the el torito extension?

rockridge seems to have problems:

# mkisofs -r -o suse-7.0-disk1.iso /cdrom/
Using RR_MOVED.000 for  /rr_moved (rr_moved)
mkisofs: Error: (NULL POINTER) and /cdrom/rr_moved have the same Rock Ridge
namemkisofs: Unable to sort directory

any hints?
