How old is tradition?

I'm sure the first unix system I used had users filestore in /usr
(ie home directories).
Unfortunately the disks weren't big enough to get all the system
stuff into /, so chunks of it migrated.
This isn't really necessary any more.

Even the /usr is sharable readonly between systems (eg for diskless
sun3) isn't really true in most cases.

OTOH if (most of) /bin and /sbin is shared, there is no real reason
to 'crunch' the /recover binaries just for a few MB of disk space.
Just ensure that there are enough useful utilities.

Shell performance would be improved by putting a little effort
into making more commands builtin.

Profiling the dynamic loader might show some hot spots where
performance can easily be improved.
