Simplify the management of the kernel parameter crashkernel
Currently, kexec-tools only updates the crashkernel to a new default
value only when both two conditions are met,
- auto_reset_crashkernel=yes in kdump.conf
- existing kernels or current running kernel should use the old default
value.
To address seen corner cases, the logic to tell if the second condition
is met becomes quite complex. Instead of making the logic more complex
to support aarch64-64k, this patch drops the second condition to
simplify the management of the crashkernel kernel parameter.
Another change brought by this simplification is kexec-tools will also
set up the kernel crashkernel parameter for a fresh install (previously
it's limited to osbuild).
Note
1. This patch also stop trying to update /etc/default/grub because
a) it only affects the static file /boot/grub2/grub.cfg
b) grubby is recommended to change the kernel command-line parameters
for both Fedora [1] and RHEL9 [2][3]
c) For the cases of aarch64 and POWER, different kernels could have
different default crashkernel value.
2. Starting with Fedora 37, posttrans rpm scriplet distinguish between
package install and upgrade.
