weird science experiments with init systems - part one

[bones]

Speaking of init systems, Apple's launchd is being ported to FreeBSD:

@gekko, I'd like to see some "systemd-analyze blame" or the bootchart for Pussy Muncher :) This is too Buntu for BBQ :D

Thank you, Sir. Well yes, there's quite a lot of auto-...ing going on, the printer is set up, as well as stuff to mount Windows shares. They *can* be inserted manually if not used every day. OTOH, if it doesn't disturb you and you are happy that everything works after boot, just leave as it is. cpufreq and lmsensors, for example, are not *really* needed, but they don't really disturb.

[GekkoP]

It's wife's netbook, she'll kill me (and everybody here) if I play too much with it. :D
I can safely disable cpufreq and lmsensors though, thanks for the tip.

[machinebacon]

^ If the netbook is often 'on air' I'd rather keep cpufreq so that it can save some battery life. If it's mostly on the desk, and it doesn't spin too hot, disable it.

[GekkoP]

Pidsley, have you ever tried sinit from suckless? Just curious about your opinion on it.

[pidsley]

I read a little bit about it on the Arch forum, but I have not tried it yet. If you feel motivated to try it, please do. I might get to it later this summer when it gets too hot to be outside much.

[pidsley]

Debian with busybox and eudev. No systemd, no sysv.

[GekkoP]

^ fantastic! I'll try eudev on my Gentoo asap.

[pidsley]

On Gentoo, just follow the directions in the first post in this thread: http://forums.gentoo.org/viewtopic-t-96 ... eudev.html

But udev is already separated out from systemd on Gentoo, so there is some controversy over whether eudev is really necessary. I'm still reading all the posts about whether it is or not. In any event, it is an interesting exercise.

[GekkoP]

^ perfect, thanks for the tip.

[GekkoP]

Did it. Though it is udevd and not eudevd like yours. Still, no systemd-udev in pstree output so I might have done it. :)

[pidsley]

I tweaked eudev to show up as eudev in pstree on that Debian system; it normally just shows up as udev. ;) If you removed udev and emerged eudev, you have it. You can also mask systemd and udev so they never get pulled back in. Search for "eudev" on the Gentoo forum for more about this.

[GekkoP]

^ perfect, thanks. So I did it right. I'll go looking for that masking then. This is a really nice experiment.

[elixir]

^ GekkoP you have 1234 posts. This is an honor to see.
