Do you change the mountp= oint > property of zroot/ROOT/*/usr on the inactive BE's to avoid that? Yes, exactly. It's all described in the companion piece to install-on-zf= s: http://www.infracaninophile.co.uk/articles/zfs-update-management/ However, that page is in need of an update: I modified the manageBE script to automate a lot of the actions described there, and I've been intending to look at Bryan Drewery's beadm program as well. > BTW, there is a minor bug in the article (on 8.3 at least): "zpool expo= rt > zroot" fails to unmount everything because the cwd is in /tmp/zroot/etc= at > that point. Adding "cd /" beforehand fixes it. Hmmm.... yes. Fixed, thank you. Cheers, Matthew --=20 Dr Matthew J Seaman MA, D.Phil.
