Service statd does not come up:

# sv status /var/service/statd
down: /var/service/statd: 1s, normally up, want up

# ps wax | grep runsvdir
491 ?        Ss     0:00 runsvdir -P /run/runit/runsvdir/current log: rvice already running! Statd service already running! Statd service already run

Removing /var/service/statd, no rpc.statd is being launched.
Launching rpc.statd -F -d by hand, the process does not stay in foreground, which I believe is the cause.
