dcc package on 3.15 has almost blank nonfunctioning init script
alpine-release 3.15.0 / dcc-openrc-2.3.168-r0 https://gitlab.alpinelinux.org/alpine/aports/-/blob/master/community/dcc/dcc.initd
Starting with this script would cause a syntax error. I guess it expects something in the start() block. When that block was removed it can't find some directores it needs for pid files etc in /var/run. I don't know enough to write a custom script and solve all the issues.
Instead, I was able to get the full init script from gentoo and start dcc with it. (Gentoo's script seemed to need /etc/dcc/dcc_conf. I worked around that issue by symlinking /etc/dcc to /var/dcc)
