I thought about 0666 too, but that means we have to pretend that the zfs
modules has no bugs ever that can be exploited.

Adding a group zfsadm and use 0660 would add a seperate security layer
in case of any bugs in the zfs module that can be used to escalate
priviledges. Even audio has its own group, and I would consider that
device far less risky than a filsystem tool.
