I did this in OpenRC source
rm -rf /home/roy/pkg
make PREFIX=/home/roy/pkg PKG_PREFIX=/usr/pkg install
Create Gentoo style init script in /home/roy/pkg/etc/init.d for say boinc
export PATH=$PATH:/home/roy/pkg/bin:/home/roy/pkg/sbin
rc-update add boinc default
rc default

boinc started

This needs to be done on startup

rc sysinit
rc default

Which is pretty much what we do in Gentoo anyway. Just ensure that the
sysinit
runlevel only runs once, as it will remove all state when run again.
