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`

rescue: don't pull in sockets In rescue mode let's not establish all sockets, so that we don't end up starting a lot of additional services automatically. Instead of pulling in basic.target we now only pull in sysinit.target which pulls in local-fs.target and swap.target. That way rescue mode has all the really basic setup around, but normal services are not started and not autostarted either. 2012-05-22 22:12:25 +08:00			`After=sysinit.target plymouth-start.service`

units: always use sulogin in rescue.service sushell makes much less sense than sulogin. If distros want to stick to sushell they should patch this downstream. 2013-01-05 05:38:11 +08:00			`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 12:22:21 +08:00			`ExecStopPost=-@SYSTEMCTL@ --fail --no-block default`
service: introduce Type=idle and use it for gettys Type=idle is much like Type=simple, however between the fork() and the exec() in the child we wait until PID 1 informs us that no jobs are left. This is mostly a cosmetic fix to make gettys appear only after all boot output is finished and complete. Note that this does not impact the normal job logic as we do not delay the completion of any jobs. We just delay the invocation of the actual binary, and only for services that otherwise would be of Type=simple. 2012-04-24 20:28:00 +08:00			`Type=idle`

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 18:11:04 +08:00			`StandardOutput=inherit`
