[pve-devel] [RFC proxmox-backup 1/1] api2/node/disks/zfs: instantiate import service

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

When creating a new zpool for a datastore, also instantiate an
import-unit for it. This helps in cases where '/etc/zfs/zool.cache'
get corrupted and thus the pool is not imported upon boot.

This patch needs the corresponding addition of 'zfs-import@.service' in
the zfsonlinux repository.
