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: make descriptions of api filesystems less generic (#5914) All those names were very generic. Fixes #5911. 2017-05-10 14:09:52 +03:00			`Description=Kernel Debug File System`
man: add Documentation= tags to all kinds of missing units 2012-06-27 03:07:04 +04:00			`Documentation=https://www.kernel.org/doc/Documentation/filesystems/debugfs.txt`
units: use https for the freedesktop url (#6227) 2017-06-29 05:54:12 +03:00			`Documentation=https://www.freedesktop.org/wiki/Software/systemd/APIFileSystems`
mount: add automatic start ordering dependencies for mounts 2010-07-13 00:55:27 +04:00			`DefaultDependencies=no`
units: drop automount unit for /sys/kernel/debug Since debugfs cannot be compiled as module there's little benefit in having it as autofs mount point. 2011-09-21 05:20:28 +04:00			`ConditionPathExists=/sys/kernel/debug`
units: conditionalize configfs and debugfs with CAP_SYS_RAWIO We really don't want these in containers as they provide a too lowlevel look on the system. Conditionalize them with CAP_SYS_RAWIO since that's required to access /proc/kcore, /dev/kmem and similar, which feel similar in style. Also, npsawn containers lack that capability. 2014-07-04 05:10:09 +04:00			`ConditionCapability=CAP_SYS_RAWIO`

units: set nodev,nosuid,noexec flags for various secondary API VFS A couple of API VFS we mount via .mount units. Let's set the three flags for those too, just in case. This is just paranoia, nothing else, but shouldn't hurt. 2019-03-25 21:39:00 +03:00			`Options=nosuid,nodev,noexec`
