drwxr-xr-x  17 5101     51           4096 Mar 23 22:20 syscd/
               ^^^^^^^^^^^^ Where does this come from? I have no
such group or user on my system?

And even more troublesome mounting disc 2:

drwx------   4 root     bin          2048 Mar 23 22:20 cd/
    ^^^^^^ No rights for any users!

This is dependant on the disc! I have two IDE drives in my system and I can
switch the CDs in the drives and the problems move over to the other drive!

Disc2 cannot be used by my BBS users since they do not have any access!!!
The directory rights are OK when the CDs are not mounted. I.E.
the regular drwxr-xr-x with owner root.bin.

Some Data for you to get a complete picture:

Kernel 1.2.3 Slackware 2.1.0
syscd = Mitsumi 4x IDE
cd    = Acer 2x IDE

fstab--------------------------------------------------------
/dev/hda2       /        ext2        defaults
/dev/hda3       /usr     ext2        defaults
/dev/hda4       /Library ext2        defaults
/dev/hdb3       swap     swap        swap
none            /proc    proc        defaults
/dev/hdb4       /new     ext2        defaults
/dev/hdc        /cd      iso9660     ro,user
/dev/hdd        /syscd   iso9660     ro,user
/dev/hdb2       /var     ext2        defaults,exec
/dev/hdb1       /home    ext2        defaults
/dev/hda1       /dos     msdos       gid=100,uid=999
/dev/fd0        /floppy  msdos       noauto,defaults,user
----------------------------------------------------------------

More strange things when I installed Slackware 2.2.0 to get its programs
from the CD. It does not allow me to mount Disc1 for exec and suid from
fstab. If I give the manual mount command everything is fine!

I had a look at the sourcecode. Seems that all the information that is
destroyed is kept in one field of the SuperBlock-Structure  called s_flags.

That's evident; otherwise it would show than names instead of the
numbers.  That's the owner of that directory on the disk.  That
is *completely* normal and correct.  Don't worry about it in the
least.

   And even more troublesome mounting disc 2:

   drwx------   4 root     bin          2048 Mar 23 22:20 cd/
       ^^^^^^ No rights for any users!

   This is dependant on the disc! I have two IDE drives in my system and I can
   switch the CDs in the drives and the problems move over to the other drive!

That's because the permissions on the root directory of the disk
are 700.  Whenever you mount any filesystem at all, the permission of
the root directory of the filesystem being mounted overrides the
permission of the directory you are mounting it on.

   Disc2 cannot be used by my BBS users since they do not have any access!!!
   The directory rights are OK when the CDs are not mounted. I.E.
   the regular drwxr-xr-x with owner root.bin.

Correct.  See above...

In answer to your second post, this is not a bug in the rock ridge
extensions, it is how the CD was burned.

I have the same problem.  I'm intending to take a look at the isofs
code to see if there's an easy way around this, but I've been too
busy...

Thanks for the Info. I will return the CDs and demand a replacement from
INFOMAGIC.

It just takes care that all directories are readable and executable
and that all regular files are readable.
