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 06:20:58 +08:00			`# 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 21:12:18 +08:00			`Documentation=man:systemd.special(7)`
units: downgrade dependency on sockets.target/timers.target/paths.target by basic.target There isn't really any need to require any targets but sysinit.target from basic.target, so downgrade sockets.target, paths.target, timers.target. 2013-03-26 09:32:20 +08:00			`Requires=sysinit.target`
units: add default units for system.slice, user.slice, machine.slice 2013-06-18 06:59:54 +08:00			`Wants=sockets.target timers.target paths.target slices.target`
units: downgrade dependency on /tmp in basic.target to Wants= Now that requiring of a masked unit results in failure again, downgrade the dependency on /tmp to Wants= again, so that our suggested way to disable /tmp-on-tmpfs by masking doesn't result in a failing boot. References: #2315 2016-02-10 03:34:27 +08:00			`After=sysinit.target sockets.target paths.target slices.target tmp.mount`
units: explicitly require /var, /tmp and /var/tmp to be mounted before basic.target We support /var, /tmp and /var/tmp on NFS. NFS shares however are by default ordered only before remote-fs.target which is a late-boot service. /var, /tmp, /var/tmp need to be around earlier though, hence explicitly order them before basic.target. Note that this change simply makes explicit what was implicit before, since many early-boot services pulled in parts of /var anyway early. 2015-04-03 20:32:32 +08:00
