root is zfs.
Solaris 10 LiveUpgrade does indeed currently use ZFS snapshots. It has
for at least the last couple of Update release (I want to say it
appeared in Update 6, but I can't remember exactly). I'd have to look,
but I don't think ZFS is *currently* used for the zone scripts, though
there's no barrier for it to be used with (or inside) zones.
ZFS is a key strategic component of Solaris going forward. Having to
abandon it would be a heavy blow -- quite possibly (IMO) fatal -- at
least to its future with Oracle.

Losing ZFS would indeed be disastrous, as it would leave Solaris with
only the Veritas File System (VxFS) as a semi-modern filesystem, and a
non-native FS at that (i.e. VxFS is a 3rd-party for-pay FS, which
severely inhibits its uptake). UFS is just way to old to be competitive
these days.
