relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends. 2012-04-12 02:20:58 +04:00			`# under the terms of the GNU Lesser General Public License as published by`

units: introduce new Documentation= field and make use of it everywhere This should help making the boot process a bit easier to explore and understand for the administrator. The simple idea is that "systemctl status" now shows a link to documentation alongside the other status and decriptionary information of a service. This patch adds the necessary fields to all our shipped units if we have proper documentation for them. 2012-05-21 17:12:18 +04:00			`Documentation=man:systemd.special(7)`
units: reorder/split unit dependency blocks The block is reordered and split to have: 1. description + documentation 2. (optionally) conditions 3. all the dependencies I think it's easier to read the units this way. Also, the Conflicts+Before is seperated out to separate lines. The ordering dependency is "fake", because it could just as well be After=, we are adding it to force ordering wrt. shutdown.target, and it plays a different role than the other Before=, which are about a real ordering on boot. 2022-09-14 14:39:10 +03:00

But it could take some time to investigate, so let's re-open the issue as a first step. 2017-09-26 20:47:50 +03:00			`Wants=local-fs.target swap.target`
