service: ignore dependencies on $syslog and $local_fs in LSB scripts We no longer allow early-boot init scripts, however in late boot the syslog socket and local mounts are established anyway, so let's simplify our dep graph a bit. If $syslog doesn't resolve to syslog.target anymore there's no reason to keep syslog.target around anymore. Let's remove it. Note that many 3rd party service unit files order themselves after syslog.target. These will be dangling dependencies now, which should be unproblematic, however.

units: add reference to wiki so syslog.socket

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.

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.

socket: add option for SO_PASSEC https://bugzilla.redhat.com/show_bug.cgi?id=798760 (Note that this work is not complete yet, as the kernel seems to send us useless data with SCM_SECURITY enabled)

log: increase socket buffers for logging by default

units: make sure syslog socket goes away early during shutdown

kmsg-syslogd: remove kmsg-syslogd, since it's entirely obsoleted and replaced by journald

journal: move sockets into their own subdir

socket: rename the PassCred= option to PassCredentials=, since we don't want to needlessly abbreviate options unless they are very well established

journald: forward all syslog messages to syslogd

syslog: use PassCred=yes for the /dev/log socket Both kmsg-syslogd and the real syslog service want to receive SCM_CREDENTIALS. With socket activation it is too late to set SO_PASSCRED in the services.

units: pull in syslog.target from syslog.socket

units: order syslog.target after syslog.socket

syslog: enable kmsg bridge by default and enable syslogging for early boot services
