Hi all, while still working (slowly) on an answer to my own question on the right workflow to keep current up to date reliably with boot environments, I noticed that after creating and mounting a new BE, that new BE's /dev (eg /mnt/dev) is very sparsely populated: [22:44:45: ~ 0] $ ll /mnt/dev total 20 9 dr-xr-xr-x 4 root wheel 7 Apr 18 00:35 . 9 drwxr-xr-x 23 root wheel 30 May 5 22:44 .. 1 drwxr-xr-x 2 root wheel 2 Apr 18 00:35 fd 1 lrwxr-xr-x 1 root wheel 12 Apr 17 20:41 log -> /var/run/log 1 -rw-r--r-- 1 root wheel 63 May 3 22:19 null 1 -rw-r--r-- 1 root wheel 1 May 3 22:18 null.bak 1 drwxr-xr-x 2 root wheel 2 Apr 18 00:35 shm [22:44:48: ~ 0] $ (no matter whether I use "beadm create" or "bectl create -r") I can then mount devfs: # mount -t devfs devfs /mnt/dev and it will look (and work) as expected (eg for "pkg -c /mnt update" (*)) ... as long as the BE is mounted. When I try to boot from (into?) that BE though, it fails, and on the console I can see messages about missing /dev/... entries. I sneaked a peek into beinstall.sh, found no inspiration there, I'm afraid. I believe I noticed this apparent requirement to mount devfs separately not so long ago ... definitely this year, while I've been experimenting with boot environments for quite a bit longer. Was I just lucky all along, or did something change ... and, more importantly, how do I make my boot environments bootable again? TIA for hints, pointers, advice Michael *) I first noticed something was amiss when "pkg -c /mnt ... " complained about /dev/null missing, IIRC ... -- Michael Schuster http://recursiveramblings.wordpress.com/ recursion, n: see 'recursion'
