mkisofs "-graft-points" not working?
After installing the recent cdrtools (a35), I started a backup script
which writes all the backup information in a file and then creates an
ISO image thus:
mkisofs -o $DATE.iso -RU -graft-points -path-list $DATE.filelist
The run aborted saying that files had the same Rockridge name. After
some investigation, it appears that the conflict was caused by ignoring
the graft points and putting every file in the root of the image instead
of using the subdirectory information. The man page for mkisofs
indicates that graft-points still is intended to function as I have been
using it for years.
The symptom is that a graft point like "USRLCL=/usr/local" no longer
creates a subdirectory called USRLCL, but rather puts the tree starting
with /usr/local directly in the root of the ISO image. Needless to say,
this change doesn't qualify as an enhancement with me.
Just a warning, started quite a while ago, perhaps as long ago as a26.
I'm sure that there's some obscure option to make graft-points work as
they used to, and I'll be told to read the manual (as usual), and it's
all a kernel problem (as usual), or it's my hardware (as I was told last
week), but at the moment mkisofs doesn't have working graft-points.
Simple test:
posidon:davidsen> cd /tmp
posidon:davidsen> mkdir AA BB
posidon:davidsen> touch AA/temp
posidon:davidsen> touch BB/temp
posidon:davidsen> mkisofs -o x.iso -RU -graft-points DirAA=AA DirBB=BB
Warning: creating filesystem that does not conform to ISO-9660.

Unknown file type (unallocated) AA/.. - ignoring and continuing.
Using temp000 for /temp (temp)
mkisofs: Error: 'BB/temp' and 'AA/temp' have the same Rock Ridge name

Trying without graft-points it seems to work:
posidon:davidsen> tree -d
.
|-- AA
`-- BB
2 directories
posidon:davidsen> mkisofs -o y.iso -RU .
