[arch-general] Anything to manage user daemons?
Hello. I need to start several programs after login and after startx. Now I write these directly in my .bash_profile and .xinitrc; but I'm not satisfied with this. They cannot be easily stopped after logout. To do that I think I'd record their PID and kill them in .bash_logout, also need to take care when they're manually stopped, and all these related problems. So I think a set of scripts like the daemon managing from initscripts will be nice. But I can't write /etc/rc.d daemons, as they must be executed by a normal user. Has anyone written such a tool?

those look neat. I wonder how they compare to each other and to systemd (which is designed to deal with system- and user level daemons as well) Dieter
Yes I am also curious about this, systemd (which I've been using for some time) would appear to be the ideal solution to this. However I find the interface for controlling daemons etc (using commands like `sudo systemctl restart openntpd.service') to be somewhat clunky. Maybe someone knows of a more elegant way to use systemd so as to not require extra tools like supervisord/daemontools? -- Evan LeCompte On Mon, Jun 20, 2011 at 3:51 AM, Dieter Plaetinck <dieter@plaetinck.be>wrote:

Instead of doing exec startx, you can background startx and wait for it, allowing your script to complete and clean things up. I don't know of a specific tool for managing user processes though, however you could "copy" rc.d/? files and amend them for your own usage. ~/.xinitrc: #! /bin/bash start stuff startx & wait $? stop stuff
How about using /etc/rc.d/ scripts with 'su user' to start the program as the relevant user (as per the rtorrent wiki suggestion, https://wiki.archlinux.org/index.php/Rtorrent#rtorrent_Daemon_with_screen), and then sudo permissions to run 'sudo /etc/rc.d/foo start/stop' in .xinitrc and .bash_logout?

yuck. if you just want to manage daemons running as your own user, su and sudo shouldn't even be involved. On Wed, 22 Jun 2011 11:05:35 +0100 Owain Sutton <mail@owainsutton.co.uk> wrote:

I have to disagree. Some daemons run as a different user like httpd or mpd for instance. They are started by root but are su'd to the user needed. I don't see any need to run an actual "user" daemon but if I did, that would be the way I would do it.

This is not a disagreement, rather a different interpretation of "user daemon". For me "user daemon" means a daemon running as the same user I'm logged in as. Daemons running as httpd or mpd probably need to be started as root indeed - I'm not aware of a better method -, but I just don't call those "user daemons", they are regular daemons to me. Dieter
