I don't understand
kdumpctl reset-crashkernel
The users can run "kdumpctl reset-crashkernel" manually to reset
crashkernel to the default value.
What does this do ?
The new kdump.conf has :
auto_reset_crashkernel <yes|no>
And this option is for the users to choose whether to let kexec-tools
automatically reset crashkernel to new default value after kexec-tools
updates its default value when kexec-tools find a kernel is using
the old default value for the crashkernel parameter.
I don't understand the usage model .
One big reason we don't use "crashkernel auto/CUSTOM-VALUE" option in
kdump.conf is the users may be used to set custom crashkernel value by
grubby and kexec-tools tries to respect that.

What if. I want to define a new crashkernel. value ? how is that down ?
crashkernel=1G-4G:126M,4G-64G:256M
Is this added to kdump.conf ?
If you want to set custom value, you need to use tools like grubby.
