sysutils/zfs-set 1.0.3_2 DragonFly

zfs-set is a terminal UI and scripting front-end for ZFS dataset properties (zfs get / zfs set / zfs inherit). It lists every property of a dataset with its value and where the value comes from (local, received, inherited, default, temporary), explains each one, edits it through a list of the allowed values with their meaning or a validated text field, and shows the exact zfs set / zfs inherit commands before running them. Pre-flight checks point out what zfs will refuse (a quota below the used space, a volsize that is not a multiple of volblocksize, a pool feature not enabled, a property the dataset type does not have) and what a change implies (mount point changes remount, canmount=off unmounts, compression and checksum affect only new data, sync=disabled is unsafe, Linux-only properties do nothing on FreeBSD). Received values can be reverted to with zfs inherit -S. All of it is also available non-interactively for scripts (-set, -inherit, -tree, -where, -dump/-restore, dry run, -check).
