units: mount /tmp as tmpfs The default setups should be a stateless as possible. /tmp as tmpfs is the intended default for general purpose systems. Small temporary files should not be stored on disk; lager files, or files which should potentially survive a reboot, belong into /var/tmp. Also catch up with some good old UNIX history.

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 00:20:58 +02:00			`# under the terms of the GNU Lesser General Public License as published by`

units: skip mounting /tmp if it is a symlink We shouldn't get confused if people have symlinked /tmp somewhere, so let's simply skip the mount then. 2014-06-30 21:44:05 +02:00			`ConditionPathIsSymbolicLink=!/tmp`
units: don't order tmp.monut after local-fs-pre.target Since tmp.mount is a tmpfs this is not necesary, and should speed up boot marginally. 2012-10-23 22:33:00 +02:00			`DefaultDependencies=no`
