Unfortunatly not! "zpool create" tries to write to /boot/zfs/.zpool.cache
(possibly a temporary) which cannot be written. If I symlink
/boot/zfs/.zpool.cache -> /etc/zfs/.zpool.cache, I end up with the
cache being written to /etc/zfs/.zpool.cache. This file however is then not
copied or moved to /etc/zfs/zpool.cache, but of the symlinks.
If I link /boot/zfs/.zpool.cache to /etc/zfs/zpool.cache, the file is
populated.
After a reboot however the file, which was copied there by the rc.initdiskless,
seems not to containt, what zfs expects, since the filesystems are not
mounted and I need to import the pool by hand.

Best Regards,
Oliver
