setup-alpine enabled urandom init.d service which has been replaced by latest openrc version
In Alpine Edge openrc was recently upgraged to 0.45.2. In this version of OpenRC the /etc/init.d/urandom script has been replaced by /etc/init.d/seedrng.
However setup (from alpine-conf) enables the urandom init.d service - this needs to be changed and I have raised alpine-conf!86 (closed) for this change.
A new version of alpine-conf should be released and then the package updated in aports.
