====== Mountpoints ======

===== change mountpoint =====

<code bash>
zfs set mountpoint=none backupool
zfs set mountpoint=none backupool/BACKUP
zfs set mountpoint=/BACKUP backupool/BACKUP
</code>

===== allow user to create new datasets =====
<code bash>
sudo zfs allow -u USER create,mount,destroy,refreservation pool/path/to/prj

# list permissions
zfs allow pool/path/to/prj
</code>

===== alternate root =====
  When a pool is created, the pool is intrinsically tied to the host system. The host system maintains knowledge about the pool so that it can detect when the pool is otherwise unavailable. While useful for normal operation, this knowledge can prove a hindrance when booting from alternate media, or creating a pool on removable media. To solve this problem, ZFS provides an alternate root pool feature. An alternate root pool does not persist across system reboots, and all mount points are modified to be relative to the root of the pool. 
  
To change alternate root runtime:
<code bash>
zpool export backuppool
zpool import -R /fakeroot backuppool 
</code>

To remove alterante root:
<code bash>
zpool export backuppool
zpool import backuppool
