Good question, not silly. The answer is I don't know -- when I moved from RELENG_9 to RELENG_10, I reinstalled straight from memstick here: ftp://ftp4.freebsd.org/pub/FreeBSD/snapshots/amd64/amd64/ISO-IMAGES/10.0/ I always install -STABLE and not -RELEASE because for nearly 15 years I've found too many broken things in -RELEASE that don't get fixed soon enough for me. I can try "rolling back" in SVN to r256281 and try that (I'm afraid to find out what buildkernel/buildworld will break on though, heh). I think that's the rev as close to 10.0-RELEASE as possible? http://svnweb.freebsd.org/base?view=revision&revision=256281 -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Making life hard for others since 1977.
