Description Eugene Grosbein 2011-06-19 11:50:07 UTC 
	I'm trying to use FreeBSD-8.2-RELEASE-amd64-livefs.iso
	with additional configs (rc.conf etc.) to boot remote system from.
	Then I login using ssh and try to 'su' to root but it fails:
	/usr/bin/su in the image has no SUID bit.

Fix: 

Unknown. It would be nice if next release have this problem fixed.
How-To-Repeat: 
# md=`mdconfig -af FreeBSD-8.2-RELEASE-amd64-livefs.iso`
# mount_cd9660 /dev/$md /mnt/tmp
# ls -l /mnt/tmp/usr/bin/su
-r-xr-xr-x  1 root  wheel  16904 Feb 17 08:19 /mnt/tmp/usr/bin/su

	All other binaries that should normally have SUID/SGID
	do not have them too.

This is not a bug (it's a feature!). A cd9660 file system does not know
anything about suid/sgid bits (and even group or owner). It is not a
"unix like" file system.

You can't avoid this behavior.

Incorrect. Indeed, cd9660 does not know about files permissions
but Rockridge extention to cd9660 does. And our mount_cd9660 uses
Rockridge by default, so this bug is avoidable by using right permissions
and Rockridge while generating image (mkisofs -R, not mkisofs -r).
