<p>An update that contains one feature and has 11 fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for kernel-livepatch-tools fixes the following issues:</p>
<p>Version 1.8:</p>
<ul>
<li>
<p>Drop different flavors support (bsc#1245949)</p>
</li>
<li>
<p>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.</p>
</li>
<li>
<p>Use "transactional-update" for downgrading livepatch package
on transactional systems (bsc#1245346)</p>
</li>
<li>
<p>Improve the description of the LIVEPATCH_KERNEL sysconfig variable
(bsc#1236642)</p>
</li>
<li>
<p>Use dracut to regenerate initrd when "mkinitrd" can't be
found (bsc#1234757)</p>
</li>
<li>
<p>Remove week dependencies on SLE16+ to unify the behavior on
SLES, SLES Minimal, and SL Micro (bsc#1219966)</p>
</li>
<li>
<p>cache-cleaner: Correctly handle situation when there is no livepatch
loaded (bsc#1231422)</p>
</li>
<li>
<p>klp-info-cache.service: Expand %%{_libexecdir} when setting
ExecStart. The cache-cleaner script has been moved in SL Micro 6.0
(bsc#1231397)</p>
</li>
<li>
<p>klp.sh: Fix downgrade with skipped package version (bsc#1223966)</p>
</li>
<li>
<p>klp.sh: Exit with an error code when downgrade fails (bsc#1223930)</p>
</li>
<li>
<p>kernel-livepatch-tools-devel produces livepatch packages
compatible with kernel-livepatch-tool >= 1.2</p>
</li>
<li>
<p>Fix installation paths for SL Micro 6.0 (jsc#PED-8219):</p>
<ul>
<li>%%{_libexecdir} newly pointing to /usr/libexec; update macros
calling kernel-livepatch/rpm-helper accordingly</li>
<li>dracut files stay in /usr/lib/dracut</li>
<li>rpm files stay in /usr/lib/rpm</li>
<li>kernel modules are installed under /usr/lib</li>
</ul>
</li>
<li>
<p>Keep backward compatibility with SLE15:</p>
<ul>
<li>install the rpm macros in %%{_sysconfdir} when built for
SLE15 code base</li>
</ul>
</li>
<li>
<p>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.</p>
</li>
<li>
<p>Remove klp-convert from kernel-livepatch-tools-devel (bsc#1218644)</p>
</li>
<li>
<p>Move RPM macros away from /etc as hinted by RPMLINT</p>
</li>
<li>
<p>klp.sh, rpm-helper: Cache live patch metadata (bsc#1191344)</p>
</li>
</ul>
