Sorry -- I can't explain that.

There's more than one way to do it. If your situation permits you to
use -maproot=root, then the nfs mount is just like any locally mounted
partition (except for the sharing thing).

First of all, "make build" normally cleans the tree, unless you set
UPDATE=yes. Even with UPDATE, if your clients are all the same
platform, then it doesn't matter. If they're different archs, you can
set 'OBJMACHINE=yes' in "/etc/mk.conf", and the objdirs will take the
form "obj.<machine_arch>". You can do even more with MAKEOBJDIRPREFIX,
but I've never used that. (See /usr/share/mk/bsd.README for details.)

Or, you can set BSDOBJDIR to a local directory, and then only a
symlink gets created in the shared sources. That works fine, too.
Sharing the kernel build dirs isn't much of a problem, since each
client will probably have it's own kernel.

For "xsrc", you need write privs on the source dir, and it's a good
idea to run "make cleandir" on the old platform before switching to
the new one. Fortunately, there's not as much to build there as for
the base system, nor does it change as often.
