You inspired me. Maybe I can build a NTP server on my Rasp Pi in the local network and sync from it. It should be a little bit faster and save me...well, 3 seconds ;-)

I do not; I have found a few public stratum 1 servers relatively close to me, and I use them in general, via their IP addresses and not via their DNS names. On my desktop and on my Pi, which do not need mobility, I don't even do that: I sync to my router.

Well, to play the anti-$DEITY advocate, you may also say that parallelizing helps you discover bugs in the dependencies that you otherwise never would. I have run fedora with systemd for a while, and I was able to make the boot wicked fast. But it wasn't automatic, not due to systemd itself but due to packages like NetworkManager doing incredibly wasteful things by default. -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.

Having more parallel boot operations used to be one of the "advantages" touted by some pro-systemd people. I always thought it sounded like a horrible idea and an excellent reason to stick with openrc. I have enough problems figuring out package build failures with -j2. :/ -- Grant
