So we have established that the ZFS is not bootable in Solaris 10 as
yet. I kinda suspected that was the case as ZFS is still in it's
early stages. Does anyone know if my other suggestion, of a partially
ZFS enabled install, is possible?
Maybe if you use a small, say 9GB, disk as your swap and '/' and only
partitioned those during the install, then directly after that stage
in the installer (trying to remember the sequence here) dropped to a
console and setup your zpool and filesystems, and mounted them to the
required directory (which I can't remember off the top of my head, is
it '/a' ?)so the installer assumes them to be subdirs of the created
root filesystem. This would possibly require a boot to single user
*before* you actually booted solaris proper to reassign the zfs
mountpoint variables for each filesystem to their correct locations
('/<dir>' rather than '/a/<dir>').
What I don't know is if you would have to export the filesystems
after the install (booted from the DVD) and then import them in
single user mode before booting Solaris off the hard disk.
Requires experimentation methinks :o)
