zvol_wait
wait for ZFS volume links to appear in /dev

zvol_wait

When a ZFS pool is imported, the volumes within it will appear as block devices. As they're registered, udev(7) asynchronously creates symlinks under /dev/zvol using the volumes' names. zvol_wait will wait for all those symlinks to be created before exiting.
