Affected Products:

  * SUSE Linux Micro 6.1
  * SUSE Linux Micro Extras 6.1

  
  
An update that contains one feature and has two fixes can now be installed.

## Description:

This update for systemd fixes the following issues:

  * Maintain the network device naming scheme used on SLE15 (jsc#PED-12317) This
    shouldn't cause problems as predictable naming schemes are disabled on
    SLMicro-6.1 (net.ifnames=0 is set on the kernel command line by default).
    Add patch for the description of these schemes in the relevant man page.
  * udev: allow/denylist for reading sysfs attributes when composing a NIC name
    (bsc#1234015)

  * journald:
    * close runtime journals before their parent directory removed
    * reset runtime seqnum data when flushing to system journal (bsc#1236886)

## Special Instructions and Notes:
