   - rules: Add by-id symlinks for persistent memory. (bsc#1140631)
   - Drop the old fds used for logging and reopen them in the sub process
     before doing any new logging. (bsc#1154948)
   - Fix warnings thrown during package installation (bsc#1154043)
   - Fix for systemctl hanging by restart. (bsc#1139459)
   - man: mention that alias names are only effective after 'systemctl
     enable'. (bsc#1151377)
   - ask-password: improve log message when inotify limit is reached.
     (bsc#1155574)
   - udevd: wait for workers to finish when exiting. (bsc#1106383)
   - core: fragments of masked units ought not be considered for
     NeedDaemonReload. (bsc#1156482)
   - udev: fix 'NULL' deref when executing rules. (bsc#1151506)
   - Introduce function for reading virtual files in 'sysfs' and 'procfs'.
