sysutils/zfs-allow 1.0.4_2 FreeBSD

zfs-allow is a terminal UI and scripting front-end for ZFS delegated administration (zfs allow / zfs unallow). It shows the delegations of a dataset the way zfs allow prints them, lets you edit them as a checklist in which every permission is described, and turns the edits into the exact zfs allow / zfs unallow commands, shown for review before they run. Pre-flight checks point out what the commands will not achieve: create without mount, vfs.usermount=0, a mount point the grantee cannot create directories in, what an unprivileged delegator cannot do. It also shows the effective permissions of a user on a dataset with their sources, and offers all of that non-interactively for scripts (-add, -remove, -effective, -where, -dump/-restore, dry run, -check).
