I dislike the redundant MAKEOBJTREE (since BSDOBJDIR already contains that location). Actually, isn't the only thing required here a *boolean* variable, complementary to NOOBJ and NOOBJLINK in bsd.obj.mk? Done right, this would mean that people not using bsd.*.mk (once sys.mk is fixed) shouldn't be affected by the possibility of having stuff go off to an obj tree they know nothing about. Jordan, I haven't played with it enough, but did you find problems which made it *necessary* to teach make(1) about /usr/obj? Can the bsd.obj.mk rules be made to do what they look like they should? (Only bsd.obj.mk seems to use BSDOBJDIR instead of /usr/obj - similarly for BSDSRCDIR - was this brought in from NetBSD recently?) I'll gladly poke in this stuff further, but if you could confirm whether you've already found the above approach unworkable, or pass on details of what fell over if you tried it and gave up...
