Moving sources (base/ports) from /usr

[Ede Wolf]

Thanks very much for answering.

That seems like a quite legit way to do this. If I am not mistaken, your 
idea is also what Dragonfly is doing, when been given it a /build 
partition during boot. As a side note.


However, the insteresting question behind using variables, from a 
beginners point of view, is, while they all relate to building stuff, 
why do all of those have to be defined in different places?


Like WRKDIRPREFIX in make.conf (according to portmaster(8)), 
MAKEOBJDIRPREFIX in src-env and absolutely not in make.conf (why ever), 
while DISTDIR seems to be an environment variable, that would imply 
/etc/profile (or csh equivalent)

(https://wiki.freebsd.org/DESTDIR, albeit quite old). And of course 
portsnap has it's own set of variables in its own config.



Anyway, for the record, so far I've managed to move /usr/src by 
accidentally having read some message that it is called SOURCEDIR, not 
SRCDIR. A first step.

make.conf may not be the best place to define this, but in lack of a 
more appropriate place it seems to work. I may play around moving this 
definition.

The only really documented variable, MAKEOBJDIRPREFIX= in src-env.conf, 
throws a lot of warnings to use ?= instead (something that at first 
glance would absolutely foil the whole idea behind it), but seems to 
work as well.
At least I've managed to build and install world that way with the src, 
ports and obj folders having been completely deleted below /usr.

While the nullmount option may eventually be the way to go for a more 
serious box, out of curiosity I'll try to get it up and running this way 
as well. And more importantly, going to understand this multitude of 
places. If possible for a mere mortal.

Have not found time to gig into ports, but
WRKDIRPREFIX and DISTDIR are the ones to set here. PORTSDIR seems only 
to be used by portsnap. But have to try these as of yet.

I do rememeber having read somewhere that WRKDIRPREFIX may also be used 
for buildworld, but have so far not been able to find this information 
again.

But thanks again very much for getting back. And if someone has some 
logic to share behind all this, I'm all ear.
