Features:
+* turn $NOTIFY_SOCKET back into an abstract namespace socket for
+ compatibility with services which chroot()
+
* exclude processes marked with argv[0][0]=@ from the normal service killing too
* support rd.luks= kernel cmdline params in cryptsetup generator
* support rd.driver= kernel cmdline params in modules load
-* supprto rd.xxx wherever else makes sense
-
* systemctl: when stopping a service which has triggres and warning about it actually check the TriggeredBy= deps fields
* journal: hook up with EFI firmware log, new kmsg logic
* when a service has the same env var set twice we actually store it twice and return that in systemctl show -p... We should only show the last setting
-* add man page documenting all kernel cmdline options, including stuff like fsck.mode=
-
* support container_ttys=
* journald: make configurable "store-on-var", "store-on-run", "dont-store", "auto"
to syslog is enabled. These settings
may be overridden at boot time with the
kernel command line options

enabled at the same time care is taken
