You can catch these errors into a logfile - see option rc_logger in rc.conf. As per a comment there, it won't log the sysinit runlevel, but that's just a few services and you can see that level start up on the screen before X takes over. By the way, no problems here with rc_parallel either. And the speed is cool. -rz

Have anyone experienced any trouble setting rc_parallel to YES? Obviously, the answer to this is YES. If no one had a problem with this, first, there wouldn't be a warning; and second, it would be enabled by default. Sure that some people use it without much problem, but if you enable it, be sure to keep it in your mind that you enabled it, and disable it if you have problems before opening any bug report having to do with system services and/or the init process.

But it helps a lot with local.start. For example: to save some boot time I mount all the non-important stuff, /mnt/movies for example, in local.start. Saves a couple of seconds and it isn't a problem that I am not able to access them while typing my password. -- #163933

Maybe not what you're looking for, but if you are really interested in truly parallelizing the startup of services you could try systemd. I use it in all of my boxes, and the boot time saved is in some cases in the order of one minute.

So, it's a feature that has always been broken, in all the stable and experimental init systems that Gentoo has had since it was born. I hope that can give you a better overview on what I meant above. In any case, placebo effects aside as always, all you'll gain from this will be a couple of seconds. In my case, I have to start eth0 to eth5 (yes, 6 eth's), and the speedup is quite significant :-) In that case, maybe systemd or a custom init script (even something simple in local.start) could greatly improve your boot time without breaking it. I don't mean you shouldn't use that feature though, I just mean that you should be vigilant if you use it. It might just work for your particular configuration, but it might also break at any random moment tomorrow so you'll need to keep an eye on it and remind to turn it off if some paranormal activity is detected in your machine or something happens to your kittens. :) -- Jesús Guerrero Botella
