I have never done such a thing, and besides, these days, replacing
/usr/lib is a couple of minutes work.

I tend to make everything the one partition, so that is pretty easy. :)

Thats why I like having one big partition. On a 120G drive, I don't
like deciding /usr/pkg needs N gigs and /home needs M gigs etc. I just
make it one big partition and I rarely have trouble. I used to spend
lots of time symlinking crud back and forth because of space
misallocations -- it no longer happens...

I blow away my machines rather frequently -- it is unusual for
something to remain lying about for long.
