I prefer grub too, but all you need to do (in either case, grub or
lilo) is add
init=/bin/sh
to your kernel command line. The root partition will be mounted ro
and instead of running /sbin/init (like usual) which goes through your
init script, the kernel will start /bin/sh as the parent process.
Thus you'll have a root shell with _nothing_ started up. You can then
remount the root partition and do what you need to do, then reboot.
I've needed to use this feature a few times before. Obviously,
though, this provides a (potential) way for an unauthorized user with
console access to obtain root privileges and change the password (or
do whatever). With grub you can protect against this by requiring a
password to do anything other than select certain predefined entries.
