- Import commit 21827ea0875ff197e16e72003b2bfaa1c6e8daad
  1ad06735f core: fail when syntactically invalid values for User=/Group= fields are detected (bsc#1047023)
  d563972e2 timesyncd: don't use compiled-in list if FallbackNTP has been configured explicitly
  f4e0c16f5 gpt-auto-generator: fix the handling of the value returned by fstab_has_fstype() in add_swap() (#6280)
  e1345aac5 fix add_esp() in the gpt-auto-generator.c (#6251)
  c591ece9a automount: don't lstat(2) upon umount request (#6086) (bsc#1040968)
  643ab2eea gpt-auto-generator: disable gpt auto logic for swaps if at least one is defined in fstab
  f07d2022f fstab-util: introduce fstab_has_fstype() helper
  bf735bb35 fstab-util: don't eat up errors in fstab_is_mount_point()
  a4b40fbed resolved: simplify alloc size calculation (bsc#1045290 CVE-2017-9445)
  8b960bec0 only check signature job error if signature job exists (#6118) (boo#1043758)
  1418bfb5b job: Ensure JobRunningTimeoutSec= survives serialization (#6128) (bsc#1004995)
  19b6d5f08 udev: turn off -Wformat-nonliteral for one safe case
  717ace439 udev: net_id add support for platform bus (ACPI, mostly arm64) devices (#5933)
  a3bf2e6b5 core/mount: pass "-c" flag to /bin/umount (#6093)

- Add minimal support for boot.d/* scripts in systemd-sysv-convert (boo#1046750)
  While at it, the handling of the symlink priorities is also removed
  since it doesn't appear to be used at all.
