(9.2-Beta 1). You cannot use "freebsd-update" to upgrade your 9.1-Release to 9.2-Beta 1 because there was a problem, but this will be resolved for 9.2-Beta 2 in the next days or weeks. > Just my .2 cents > > Kind regards, > Alexandre Hi, Whats the best list to submit oddities regarding freeBSD 9.2 Beta 1? Specifically, this line in 9.1 creates and mounts the fs under /mnt; zpool create -o altroot=/mnt -o cachefile=/var/tmp/zpool.cache zroot mirror /dev/gpt/disk0 /dev/gpt/disk1 But in 9.2 beta 1, its under /mnt/zroot. Just seems a bit odd is all. - aurfhome | help
