Or, if you have installed some kind of bootmanager that gives you a menu,
add "ro" to the bootprompt (and maybe an "S" for single-user mode, too).
Once you get a login prompt, do your tune2fs, remount / rw, and that's
it. :-)
Btw: If you want even finer control about the mount options of the root
filesystem, see the "rootflags=" option (as listed in the kernel source's
Documentation/kernel-parameters.txt) and "rootfstype=". In your case, the
following should all do the same (without warranty, just gathered from
various manpages and documents), when entered at LILO's prompt (for example):
<kernel selection> ro
<kernel selection> rootflags=ro
<kernel selection> rootflags=noload
