- The location of the udevadm binary was changed from /sbin/ to /usr/bin
a while back. A symbolic link was added for compatibility. In the latest
versions, that symbolic link has been removed, requiring changes to scripts
that were depending on that.
Added the following patches for bsc#1171587
* s390-tools-sles15sp2-lsluns-try-harder-to-find-udevadm.patch

Subject: [PATCH] [BZ 186939] zipl: prevent endless loop during secure IPL
|
|
From: Stefan Haberland <sth@linux.ibm.com>
|
|
|
|
Description: zipl: prevent endless loop during secure IPL
|
|
Symptom: During IPL with secure boot enabled the loader may loop
|
|
infinitely.
|
|
Problem: In case secure boot is enabled but no components in the
|
|
IPL report are found it ends up in an endless loop in
|
|
the component verification.
|
|
Solution: To prevent this check if components are found and exit
|
|
if not.
|
|
Reproduction: IPL with secure boot enabled.
