[pve-devel] [PATCH installer v2 3/4] fix #1410: zfs: create /var/lib/vz as separate dataset

[Stoiko Ivanov <s.ivanov@proxmox.com>]

this enables the users to set reservations on / separate from
/var/lib/vz - where backups, ISOs, and other data might fill the
complete pool.

moved the creation of the root-dataset above the creation of
rpool/data, so that the pve-specifics can remain in one if block.
