It used to be in the man page but I see it's no longer there. Here's what is in the man page on an old RH system of mine:
If you don't want to allow users to become root on your
system, cdrecord may safely be installed suid root. This
allows all users or a group of users with no root privi?
leges to use cdrecord. Cdrecord in this case checks, if
the real user would have been able to read the specified
files. To give all user access to use cdrecord, enter:
chown root /usr/local/bin/cdrecord
chmod 4711 /usr/local/bin/cdrecord
To give a restricted group of users access to cdrecord
enter:
chown root /usr/local/bin/cdrecord
chgrp cdburners /usr/local/bin/cdrecord
chmod 4710 /usr/local/bin/cdrecord
and add a group cdburners on your system.
Never give write permissions for non root users to the
/dev/scg? devices unless you would allow anybody to
read/write/format all your disks.
The above should still apply (set the SUID bit).
