I'm right? A single build machine can cross-build for multiple environments so you really only need one machine. >One last question: I would expect the same issues if I wish to to support = many >FreeBSD releases running of one single type of architecture? (i.e.: both b= uilder >and targets are amd64 machines, but I run RELENG_7 on the builder and >RELENG_6_4 and RELENG_7_1 on the targets) In general, backward compatibility is supported, so a world built on a RELENG_7 box should be able to be installed by a RELENG_7_1 target (though not by a RELENG_6_4 target). And you can run into he same problem with different i386 variants - if your build machine is built with (eg) P4 options than a generic world built by that box cannot be installed by (eg) a P2 due to instruction differences. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --CblX+4bnyfN0pR09 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAklvwj0ACgkQ/opHv/APuIegpACfWKtWC+t/iESLJVjpRQ6mq/lX JPYAmQHdSSR1/AG6M5P0NktdAGB8PkLm =xJ6f -----END PGP SIGNATURE----- --CblX+4bnyfN0pR09--
