systemd - getting started?
Hi, I liked sysv-rc for the same reason I still use my TI-89. I know how it works and I know how to use it. I think I can see the merits of systemd though. It would be nice if someone could update the wiki with some links for getting started though. At present, the wiki makes it look like systemd is not ready for anything and is incredibly buggy. This probably isn't helping. Things that have been fixed should probably be removed from the wiki page (they'd remain in the history of the page, so we don't lose them). Things I'd like to see are: * A systemd primer (like what is a service file?) * Packaging documentation for systemd (some has been started [1]) * How to hack together a service (this is something I did quite a lot for homebrew scripts on servers) There are probably other things that others would like to see too. I can see a lot of enthusiastic systemd supporters on the list, so I'm sure someone has the knowledge that I'm seeking. If someone can even just provide a braindump I'll wikify it. I'll be packaging a lightweight database system soon and I'm going to need to know what to do about the init system scripts for it. Sorry if this has already been covered, but this list has been so active with argument lately that I may have missed it. Thanks, Iain.

Hi Iain, I recommend http://0pointer.de/blog/projects/systemd-docs.html for starters. Sincerely, Jan. On Wed, Feb 12, 2014 at 12:50 PM, Iain R.

Re: systemd - getting started?
Hi! In fact, I installed systemd on my jessie system just yesterday. So far I filed two (not very major, promptly being dealt with) bugs and after a lot of initial conservative scepticism, I'm quite excited especially by journald. :) I found switching to systemd trivial by just following: /usr/share/doc/systemd/README.Debian After a reboot, I just played with various systemctl, journalctl and loginctl commands to get a feeling of it. My first experience with a service file has been following https://wiki.archlinux.org/index.php/Systemd_FAQ#Q:_How_do_I_avoid_clearing_the_console_after_boot.3F (note that on Debian, stock service files live in /lib/systemd, not /usr/lib/systemd). My rsyslog prints all logs to /dev/tty12 and it continued to do that just fine after a switch to systemd, but I decided I like the color coding provided by journalctl and thus wrote my first systemd service file that'll make journalctl run permanently on /dev/tty12, printing new log entries. I described what I got (after 10 minutes, incl. reading manual and debugging) on: http://log.or.cz/?p=327 http://pasky.or.cz/dev/systemd/journal@tty12.service Hope that's useful, Petr Pasky Baudis -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe.

I can see a lot of enthusiastic systemd supporters on the list, I'm not quite sure I qualify as one :) But I'd still like to recommend Neil Brown's excellent article series on LWN: http://lwn.net/Articles/584175/ http://lwn.net/Articles/584176/ You'll have to subscribe to read those now (or wait). But I assume the Debian developers group subscription still applies? Ref http://lwn.net/Articles/13797/ I'm not a DD, so I cannot verify that... Anyway, LWN is certainly worth paying for, even if you're not going to use systemd :-) Bjørn -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Hi, Bjørn Mork: http://lwn.net/Articles/584175/ http://lwn.net/Articles/584176/ You'll have to subscribe to read those now (or wait) … or find somebody who generates free links to the articles in question. Since LWN's subscriber link page says that these links may be given to others, which is not quite the same as publish to a widely-read mailing list, I will not post these here without asking first. Anyway, LWN is certainly worth paying for Strongly seconded. -- -- Matthias Urlichs signature.asc Description: Digital signature

Hi, http://lwn.net/Articles/584175/ http://lwn.net/Articles/584176/ Part 1 is now no longer behind the paywall.
