ACK

FYI, systemd docs say

       PartOf=
           Configures dependencies similar to Requires=, but limited to
           stopping and restarting of units. When systemd stops or restarts
           the units listed here, the action is propagated to this unit. Note
           that this is a one-way dependency — changes to this unit do not
           affect the listed units.

we clearly don't want 'restart' propagated to virtlogd
or virtlockd - those units must only ever 'reexec'
themselves.

Daniel
