I want to play with dcron but I'm having a user issue..

I linked /etc/sv/dcron to /etc/runit/runsvdir/current/dcron
and started the service but I get
run: /var/service/dcron: (pid 8134) 10s; down: log: 1s, normally up, want up

/etc/sv/dcron/run
-rwxr-xr-x 1 root root 40 Mar 15 12:19 run
exec /usr/sbin/crond -f 2>&1   # -f or -b ?
