ZFS "stalls" -- and maybe we should be talking about defaults?

I have verified that ZFS-on-root works reliably in all of the following scenarios: single disk, one mirror vdev, many mirror vdevs, raidz. Haven't found the time to test many raidz vdevs, I admit. :)

Combined with "boot environments" (that can be served many different ways), ZFS on root is short of a miracle.

ZFS on FreeBSD has some issues, mostly with huge installations and defaults/tuning, but not really with ZFS-on-root.

Of course, if for example, you follow stable, you should be prepared with alternative boot media that supports the current zpool/zfs versions. But this is small cost to pay.
