Boot-up time optimization

[mikebuzz]

This is about the best i can get

$this->bbcode_second_pass_code('', ' 2.317s ddclient.service
751ms systemd-udev-trigger.service
745ms nginx.service
586ms systemd-modules-load.service
443ms systemd-udevd.service
365ms systemd-logind.service
327ms dev-mqueue.mount
315ms systemd-vconsole-setup.service
309ms network.service
291ms sys-kernel-debug.mount
266ms systemd-sysctl.service
235ms tmp.mount
230ms systemd-random-seed-load.service
131ms systemd-tmpfiles-setup.service
119ms systemd-tmpfiles-clean.service
78ms systemd-remount-fs.service
78ms ntpd.service
76ms systemd-journal-flush.service
64ms systemd-user-sessions.service
41ms boot.mount

')

That looks like a world record?

Few more tweaks

$this->bbcode_second_pass_code('', '1.823s ddclient.service
928ms systemd-udev-trigger.service
608ms systemd-modules-load.service
466ms nginx.service
369ms systemd-udevd.service
341ms tmp.mount
340ms network.service

282ms systemd-logind.service
280ms sys-kernel-debug.mount
241ms systemd-sysctl.service
233ms systemd-random-seed-load.service

Very good!
That's not a boot from a SDcard or is it?

mikebuzz, this looks quite good. Would you mind sharing some of your tweaks with us? I noticed that netcfg or netctl don't appear in your data. I suppose in your case this is replaced by ddclient? With netctl I'm down to about 12s boot time. I found this article http://freedesktop.org/wiki/Software/systemd/Optimizations that suggests some systemd optimization, but haven't found time yet to see what might apply to the RPi.
