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`

man: document a few special units 2010-05-17 00:45:11 +04:00			`# See systemd.special(7) for details`

units: rename [Meta] section to [Unit] 2010-04-16 01:20:17 +04:00			`[Unit]`
units: install a few basic units by default 2010-04-13 07:18:12 +04:00			`Description=Emergency Shell`
units: update shipped unit files for DefaultDependencies= 2010-07-03 21:53:37 +04:00			`DefaultDependencies=no`
units: make fedora/single.service standard and rename it to rescue.service 2010-10-29 06:09:36 +04:00			`Conflicts=shutdown.target`
			`Before=shutdown.target`
units: install a few basic units by default 2010-04-13 07:18:12 +04:00
			`[Service]`
units: set HOME=/root when running shells 2010-09-10 18:53:53 +04:00			`Environment=HOME=/root`
units: set working directory to /root for sulogin, since sulogin is crazy 2010-09-10 19:11:29 +04:00			`WorkingDirectory=/root`
rescue: terminate plymouth entirely when going into rescue mode 2011-02-23 20:42:08 +03:00			`ExecStartPre=-/bin/plymouth quit`
units: reword rescue/emergency mode message to fit in 80chars 2012-02-15 23:06:14 +04:00			`ExecStartPre=-/bin/echo 'Welcome to emergency mode. Use "systemctl default" or ^D to enter default mode.'`
units: invoke sulogin instead of /bin/sh 2010-08-25 05:15:12 +04:00			`ExecStart=-/sbin/sulogin`
units/: use @SYSTEMCTL@ instead of hardcoded paths Especially in the case of --enable-split-usr, several units will point to the wrong location for systemctl. Use @SYSTEMCTL@ which will always contain the proper path. 2012-04-04 08:22:21 +04:00			`ExecStopPost=@SYSTEMCTL@ --fail --no-block default`
units: introduce emergency.target 2010-07-13 01:49:20 +04:00			`StandardInput=tty-force`
units: direct stdout/stderr of rescue shells to tty With output of services going to syslog by default now, the rescue shell units need to direct their output to tty explicitly. Specify stderr too, just in case. 2011-09-20 14:11:04 +04:00			`StandardOutput=inherit`
			`StandardError=inherit`
exec: drop process group kill mode since it has little use and confuses the user 2011-03-30 01:31:38 +04:00			`KillMode=process`
