Add permissions for ZFS list and send/recv |
| 9 |
|
| 10 |
zfs list uses a pipe to get info from the kernel |
| 11 |
|
| 12 |
avc: granted { write } for pid=31602 comm="dump_list_strat" path="pipe:[4471132]" dev="pipefs" ino=4471132 scontext=system_u:system_r:kernel_t:s0 tcontext=staff_u:sysadm_r:mount_t:s0-s0:c0.c511 tclass=fifo_file |

zfs send / recv is usually piped somewhere by sysadm |
| 16 |
zfs send tank@snap | ssh foo tank@snap |
