 * Do you realize how much userland code would break if we upped the namespace
 * in 2.2?

Not much, as far as I can tell.  I changed utmp.h and param.h and
recompiled world and kernel on all my 2.2 machines around here.  After
rebuilding ssh, xterm, kterm and xdm, all my machines are running
fine.  (I did this so I can dual-boot to 2.2 and 3.0, by the way.)

It is my opinion that changes of this sort (including login.conf)
should be held back from merging.  With 3.0 going totally bezerk with
smp and related changes, it seems like our releases are going to come
out of the 2.2 branch for quite a while, and we don't want it to
become stale like the 2.1 branch was.

On the other hand, if we can somehow shield this information from
userland code (didn't Joerg (?) mention adding functions to libutil to 
get these in runtime?), maybe it's even better (and no need to worry
about differences between 2.2 and 3.0, at least for this...).
