I agree that it makes little sense to make something a module when you
can't unload it anyway, but...

I put a complete set of recovery tools into my initramfses so that when
the system is completely fucked up, I have a kernel that is able to boot
until rdinit=/bin/zsh (or /bin/bb, if you prefer) takes over.

This has the added advantage of working when the root filesystem cannot
be mounted at all: a scenario which does not seem too far-fetched when
the filesystem is located on a raid array.
