Description Alois Mahdal 2015-08-12 07:20:52 EDT

On s390x, if user installed kernel-kdump using installer UI (anaconda,
as opposed to installing the package later using eg. yum) but later
removed it using rpm/yum, system could end up with corrupted zipl.conf
(in some cases even unbootable).

Description of problem

Current implementation of system/kernel-kdump content is trying to help
user with above scenario by advicing them but also by attempting to fix
the situation.  This has proved unreliable, too bold and potentially
causing more harm than good.

Replace content with new implementation based only on detecting,
explaining and advising on the problem, and leaving the solution up to
the user.

Version-Release number of selected component


How reproducible


Steps to Reproduce

 1. Run anaconda installer and select kernel-kdump to be installed

 2. On the new system, remove kernel-kdump using yum or similar
    but do not update /etc/zipl.conf

 3. Run preupg

 4. Run redhat-upgrade-tool to upgrade to RHEL7

Actual results

 *  Preupg says (in result.html or similar) it's planning to remove

 *  redhat-upgrade-tool removes kernel-kdump and attempts
    to update zipl.conf

Expected results

 *  Preupg raises HIGH risk and explains the situation in result.html.
    Solution is left to user.
Comment 4 Alois Mahdal 2015-08-12 12:57:49 EDT

 *  If kdump is installed *and* present in zipl.conf,
    => two separate HIGH risks are issued.

 *  If kdump is installed *but not* present in zipl.conf,
    => one HIGH risk is issued.

 *  If kdump is neither installed *nor* present in zipl.conf,
    => no related HIGH risk is issued.

 *  In any case,
    => no preupgrade-scripts are generated.
