An update that contains one feature and has 11 fixes can now be installed.

## Description:

This update for kernel-livepatch-tools fixes the following issues:

Version 1.8:

  * Drop different flavors support (bsc#1245949)

  * Hardcode version 1.2 when building for older distributions than SL 16.0. The
    existing livepatch packages require exactly this version. But new versions
    are backward compatible.

  * Use "transactional-update" for downgrading livepatch package on
    transactional systems (bsc#1245346)

  * Improve the description of the LIVEPATCH_KERNEL sysconfig variable
    (bsc#1236642)

  * Use dracut to regenerate initrd when "mkinitrd" can't be found (bsc#1234757)

  * Remove week dependencies on SLE16+ to unify the behavior on SLES, SLES
    Minimal, and SL Micro (bsc#1219966)

  * cache-cleaner: Correctly handle situation when there is no livepatch loaded
    (bsc#1231422)

  * klp-info-cache.service: Expand %%{_libexecdir} when setting ExecStart. The
    cache-cleaner script has been moved in SL Micro 6.0 (bsc#1231397)

  * klp.sh: Fix downgrade with skipped package version (bsc#1223966)

  * klp.sh: Exit with an error code when downgrade fails (bsc#1223930)

  * kernel-livepatch-tools-devel produces livepatch packages compatible with
    kernel-livepatch-tool >= 1.2

  * Fix installation paths for SL Micro 6.0 (jsc#PED-8219):

    * %%{_libexecdir} newly pointing to /usr/libexec; update macros calling kernel-livepatch/rpm-helper accordingly
    * dracut files stay in /usr/lib/dracut
    * rpm files stay in /usr/lib/rpm
    * kernel modules are installed under /usr/lib
  * Keep backward compatibility with SLE15:

    * install the rpm macros in %%{_sysconfdir} when built for SLE15 code base
  * Mark the package noarch. It is not architecture specific after the klp-
    convert removal. But rather be conservative and do it only for new products.

  * Remove klp-convert from kernel-livepatch-tools-devel (bsc#1218644)

  * Move RPM macros away from /etc as hinted by RPMLINT

  * klp.sh, rpm-helper: Cache live patch metadata (bsc#1191344)
