Hmm I have it permanently set in a projects/bmake tree that builds
buildworld etc fine (while producing meta files) - though its been a
month or two since last sync.

Internally we have it set in head trees too.
I don't doubt there's something lacking - just haven't noticed, sorry.

Sounds ok. 

Hmm etc/Makefile looks like it lost the ability to run mtree safely 
in a cross-build env?  The MTREE_FILTER stuff ensures that mtree doesn't
choke on unknown users and such.
How is that handled now?
