Add permissions for ZFS
zfs list uses a pipe to get info from the kernel
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
avc: granted { read } for pid=31601 comm="zfs" path="pipe:[4471132]"
dev="pipefs" ino=4471132 scontext=staff_u:sysadm_r:mount_t:s0-s0:c0.c511
tcontext=staff_u:sysadm_r:mount_t:s0-s0:c0.c511 tclass=fifo_file
zfs send / recv is usually piped somewhere by sysadm
zfs send tank@snap | ssh foo tank@snap
