Data Management Features: ZFS clonedir mountpoints under .zfs/clone
Recently announced Oracle Solaris 11.4 SRU 72 (My Oracle Support Doc ID 2433412.1) includes:
ZFS clonedir mountpoints under .zfs/clone
Setting the mountpoint of a ZFS clone to clonedir will now cause that clone to be mounted under the head filesystem's .zfs/clone directory. Doing a mkdir of a clone name in the .zfs/clone directory will create a snapshot of the dataset and then clone it. The zfs(8) man page was updated with more information.
