Ick. This should have been discussed before.

See my other reply.
And, btw, /usr/local/bin/do-mount:
#!/usr/bin/suidperl
#
$ENV{'PATH'} = "/sbin:/usr/sbin:/bin:/usr/bin";
$cmd = "mount";
while($_ = $ARGV[0], /^-/) {
shift;
$verb=1, next if /^-v/ || /^-verbose/;
$cmd = "umount", next if /^-u/ || /^-umount/;
last if /^--/;
&usage;
}
&usage unless $#ARGV == 0;
if($ARGV[0] eq "od") {
$type = "ufs"; $src = "/dev/od0a"; $dst = "/od";
} elsif($ARGV[0] eq "cd") {
$type = "cd9660"; $src = "/dev/cd0a"; $dst = "/cd";
} elsif ($ARGV[0] eq "dos") {
$type = "msdosfs"; $src = "/dev/fd0"; $dst = "/dos";
} elsif ($ARGV[0] =~ "^fd[0-9][.0-9]*") {
$type = "msdosfs"; $src = "/dev/$ARGV[0]"; $dst = "/dos";
} else {
&usage;
}
print "gonna $cmd $src " . ($cmd eq "mount"? "to": "from")
. " $dst, type $type\n" if $verb;
if($cmd eq "mount") {exec "/sbin/mount", "-t", $type, $src, $dst;}
else {exec "/sbin/umount", $dst;}
sub usage {
die "usage: do-mount [-v[erbose]] [-u[mount]] cd|dos|fd*\n";
}
Make it setuid root and simply say ``do-mount cd'' or ``do-mount -u
cd''. Don't need to be root. (Yeah, i know, it has security holes.
The drives should be mounted noexec,nosuid.)

Never trust an operating system you don't have sources for. ;-)
