Package: kexec-tools
Version: 1:2.0.7-2
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
After reading that systemd was now supported, I tried using systemd and
instead opted for installing sysvinit-core.
However, with sysvinit-core installed, kexec-load apparently doesn't run and
hence a kernel doesn't get loaded for kexec to run.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I added a few extra output lines and testing that /boot was mounted in the
kexec-load script, but kexec-load was apparently not run.
* What was the outcome of this action?
* What outcome did you expect instead?
How should I verify that kexec-load is being called on shutdown and where
the process is failing?
