Hello,
a yacy package is available (https://www.parabola.nu/packages/pcr/any/yacy/) since request #1093 but it looks like an OpenRc flavor is missing for those using it instead of systemd.

This was initially asked on the YaCy project GitHub issues tracker (https://github.com/yacy/yacy_search_server/issues/134), but hopefully there would be here some people more used to OpenRc and Parabola packaging specificities.

Best regards
