mkisofs 1.12.1 (i386-unknown-freebsd4.0)
>Description:
When using mkisofs 1.12.1 from the ports collection, hard
links in the source tree are not preserved in the ISO9660 that mkisofs
creates.
Joerg Schilling <schilling@fokus.gmd.de>, who is listed on the man page as the maintainer
says by email (7 Jul 2000):
" . . . send a bugreport to the Freebsd kernel team. Mkisofs is OK,
the bug is in the FreeBSD filesystem code."
>How-To-Repeat:
Do this:
1) make a test directory:
mkdir /tmp/exampletree
2) make a test file:
touch /tmp/exampletree/file1
3) make a link to the test file:
ln /tmp/exampletree/file1 /tmp/exampletree/file2
4) take a look and see the hard link:
ls -li /tmp/exampletree/
see (notice files have same inode):
total 0
14 -rw-r--r-- 2 mackler wheel 0 Jul 8 06:48 file1
14 -rw-r--r-- 2 mackler wheel 0 Jul 8 06:48 file2
5) use mkisofs to make an iso9660 filesystem:
mkisofs -o /tmp/iso9660.test /tmp/exampletree/
6) mount the new iso9660 filesystem:
vnconfig -cv vn0 /tmp/iso9660.test
mount_cd9660 /dev/vn0c /mnt
7) take a look and see the two files are not linked:
ls -li /mnt
see (notice files have different inodes):
total 0
47172 -r-xr-xr-x 1 root wheel 0 Jul 8 06:48 file1
47214 -r-xr-xr-x 1 root wheel 0 Jul 8 06:48 file2
8) clean up:
umount /mnt
vnconfig -u vn0
rm /tmp/iso9660.test
rm -rf /tmp/exampletree/
