privileges, by sending specially crafted Dbus messages.

- logind: consider "greeter" sessions suitable as "display"
sessions of a

- logind: never elect a session that is stopping as display

- journal: include kmsg lines from the systemd process which exec()d us
(#8078)
- udevd: don't use monitor after manager_exit()
- udevd: capitalize log messages in on_sigchld()
- udevd: merge conditions to decrease indentation
- Revert "udevd: fix crash when workers time out after exit is signal
caught"
- core: fragments of masked units ought not be considered for
NeedDaemonReload (#7060) (bsc#1156482)
- udevd: fix crash when workers time out after exit is signal caught
- udevd: wait for workers to finish when exiting (bsc#1106383)

- Improve bash completion support (bsc#1155207)
* shell-completion: systemctl: do not list template units in {re,}start
* shell-completion: systemctl: pass current word to all list_unit*
* bash-completion: systemctl: pass current partial unit to list-unit*
(bsc#1155207)
* bash-completion: systemctl: use systemctl --no-pager
* bash-completion: also suggest template unit files
* bash-completion: systemctl: add missing options and verbs
* bash-completion: use the first argument instead of the global variable
(#6457)

- networkd: VXLan Make group and remote variable separate (bsc#1156213)
- networkd: vxlan require Remote= to be a non multicast address (#8117)
(bsc#1156213)

- fs-util: introduce inotify_add_watch_and_warn() helper
- ask-password: improve log message when inotify limit is reached
(bsc#1155574)
- shared/install: failing with -ELOOP can be due to the use of an alias in
install_error() (bsc#1151377)
- man: alias names can't be used with enable command (bsc#1151377)

- Add boot option to not use swap at system start (jsc#SLE-7689)
