I'm so sorry for that: I'm using the Windows Live webmail=2C and it seems
impossible to have a decent message format! :(

So I actually misunderstood the Handbook: only now I realize that it
gives the suggestion to export /usr/obj and /usr/src from the build machine=
=2C
but only if the target architecture is the same as the builder! :S

Ok=2C so I think that in a production environment I should deploy one build=
er machine
for each target architecture I have to support on my network... I'm right?
One last question: I would expect the same issues if I wish to to support m=
any
FreeBSD releases running of one single type of architecture? (i.e.: both bu=
ilder
and targets are amd64 machines=2C but I run RELENG_7 on the builder and
RELENG_6_4 and RELENG_7_1 on the targets)
Thanks for your explanation.
