I can try that, but this still does not resolve the issue of md99 (I get that its not literal :) is not destroyed with the swapoff nor the fact that the swap file doesn't get put into use at all on boot. -- Tim Daneliuk tun...@tundraware.com PGP Key: http://www.tundraware.com/PGP/ ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

This was one of the worst upgrade experiences in my FreeBSD history, going back to 4.0 days.

Let's assume that you don't need a header to tell you the path of the file you are looking at. And let's leave aside why release is now releng (are we saving bytes?). And let's leave aside why the diff shows an upgrade from 10.0 to 10.2 when actually this was from 10.1 to 10.2. Can't some merge tool inside freebsd-update just sort this out for me? Please? Not only does it take over 45 minutes to go through all those files, but I feel sure I missed something. For me the majore reason to go back to - just plain STABLE installs - run mergemaster which has some tweaks to prevent diffs on versioning Compiling takes a bit of work. You kick off that during the night, and do the install next day. The upside from that is you get to deviate from what upstream thinks it should be. --WjW ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
