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 systemd-journald.service Type=notify It already calls sd_notify(), so it looks like an oversight. Without it, its ordering to systemd-journal-flush.service is non-deterministic and the SIGUSR1 from flushing may kill journald before it has its signal handlers set up. https://bugs.freedesktop.org/show_bug.cgi?id=85871 https://bugzilla.redhat.com/show_bug.cgi?id=1159641 2014-11-04 22:28:08 +03:00			`Type=notify`

units: increase watchdog timeout to 3min for all our services Apparently, disk IO issues are more frequent than we hope, and 1min waiting for disk IO happens, so let's increase the watchdog timeout a bit, for all our services. See #1353 for an example where this triggers. 2015-09-23 18:27:39 +03:00			`WatchdogSec=3min`
journald: allow restarting journald without losing stream connections Making use of the fd storage capability of the previous commit, allow restarting journald by serilizing stream state to /run, and pushing open fds to PID 1. 2015-01-06 02:30:25 +03:00			`FileDescriptorStoreMax=1024`

journal: bump RLIMIT_NOFILE when journal files to 16K (if possible) When there are a lot of split out journal files, we might run out of fds quicker then we want. Hence: bump RLIMIT_NOFILE to 16K if possible. Do these even for journalctl. On Fedora the soft RLIMIT_NOFILE is at 1K, the hard at 4K by default for normal user processes, this code hence bumps this up for users to 4K. https://bugzilla.redhat.com/show_bug.cgi?id=1179980 2015-01-08 05:17:50 +03:00			`# services being run since we keep one fd open per service.
