Re: [zfs-discuss] set mountpoint but don't mount?

Turns out setting altroot is the way to do this. Doesn't work for the root pool. Once you get to the root filesystem, mounted on /, zfs attempts to mount it. Even though you are using an altroot, / now maps to /altroot, which is of course already occupied. :( -frank _

Bob is correct to praise LiveUpgrade. It's pretty much risk-free when used properly, provided you have some spare slices/disks. At the same time, I'd say that this is probably an appropriate time to escalate the bug with support - the answers you are getting aren't satisfactory. I would also con

Once again, I find I have to correct myself: If you go to a future version of zfs, simply replace all your "full" filesystem streams with new ones, and then of course start new incrementals. Any reasonable backup procedure probably involves starting new full backups at regular intervals anyway,
