I just read up on the URL here, and thought that this would be an easy implementation of Gentoo, since the init script has depend() { need, after, before, provide } Maybe an optional configuration in make.conf? Reproducible: Always Steps to Reproduce:
it's there already, just set: RC_PARALLEL_STARTUP="yes" in your /etc/rc.conf file
Are you sure it's working properly? I'd expect to get my X running as soon as posiible but xdm always starts as the last one... :-( Radek
