It's how we build everything at work, and how we build in the freebsd.org cluster. It's way faster than a VM and generally no hassle. For the freebsd.org cluster: fetch 8.4-REL base.* -> build stage 1 -> svn checkout -> buildworld from 8.4- REL to 8-stable -> installworld in a clean chroot -> roll tarballs. fetch 9.3-REL base.txz -> build stage 1 -> svn checkout -> buildworld from 9.3-REL to 9-stable -> installworld in a clean chroot -> roll tarballs. .. and so on. For 11.x we use a ftp.freebsd.org/snapshots build. At work, we go much, much further. We even build 4-stable, 6-stable and 7- stable on 11.x hosts this way. (Why? we modify libc.so.4 to run better on 10.x/11.x and copy it from the 4.x build environment into the compat area on later releases during the build process) But we *never* cross build from head. Too many moving targets, harder to reproduce a specific build, etc. We used to have this written down somewhere. The supported upgrade path used to be explicitly documented as N.0 -> N-stable-> N+1.0, ie: 5-stable -> 6.0 -> 6-stable -> 7.0 -> 7-stable -> 8.0 -> 8-stable etc, and never in reverse. -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com; KI6FJV UTF-8: for when a ' or ... just won\342\200\231t do\342\200\246 [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAABAgAGBQJUEOJNAAoJEDXWlwnsgJ4EKnkH/2UwdWBFE7OjTQB3V3YXkLGH hUB1qinoLm4z5vQwnuL17SlKA0kP1S84lTgSJ5VxcdN8Z/bioxD0WVRLy3wZ5r7X Sq8oaIDX487BX5Da5zN0MMNPc4IGpK82LxPxdWuUEJ4t2pU2oYh4/42D2Y0FZDMN lMA/9aMfA+YPF4N3CIFo9fleUEFttshB7jSfuNO2D/vAFP1KhyGDNmotuHaZ+t1G vOF2WTUPwVesUiNRqXZV5KcBGi4ObVjkju41hpVQ8L8D63WhZz1ZKwv9Ub0z5sSP CKcc52BMyqZVl1/X4B1sGkR41Eck7K1xm1hULrVqw+vQAC8BrBYrUCTEiZxPvQQ= =OOYS -----END PGP SIGNATURE-----
