Er, I'd assumed that, if at all, you'd have done something
all-in-one-step so that the shell lands on a sane system, like this:

# cd /
# mv /lib /usr/cruciallibs && ln -s /usr/cruciallibs /lib

...and I'd still have kept that maintenance disk handy.  ;->

For whatever it's worth, the server I'm mailing this from has these
(non-swap) partitions:

Notice that / is pretty darned small, because all the significant
non-system-crucial trees are on other filesystems.

(For most purposes, dividing the system so finely would be a bit
over-maniacal:  Some of those are separate in order to use different
filesystem types or mount options, or for other special aims.)
