Parent article: Init system support in Debian

Debian parallelized the launch of sysvrc scripts (using 'startpar') long before it adopted systemd as the init daemon.

AFAIK systemd doesn't do anything particularly "clever" when it comes to parallelizing system startup, but rather just says that by default, any pair of units which do not state themselves to require serialization with respect to each other shall be assumed parallelizable.

And yet, when Debian switched over to systemd as a default, it still reduced my boot time by an order of magnitude!

(Note that I do not really have any strong opinions about init systems one way or the other. But despite switching to systemd as part of Debian's automatic updates, and, more recently, because of a re-install of my system partitions from scratch, the only difference I've observed is a faster, cleaner boot. Heck, even my log files are still working the way I'm used to. Which rather surprised me, since "I hate binary log files" is one of the few complaints I've heard about systemd that actually had me at all worried.)

I have no idea how could I have lived without journalctl --since '5 minutes ago'.

tail -200 /var/log/messages ?

(and maybe adjust your number if you guessed your log velocity wrong)

Won't list logs that live in their own files.

Not really comparable I'm afraid
