The reason I was suggesting this is that authorize?, allow-downgrades?,
safety-checks? are already part of <machine-ssh-configuration>.  These
cannot really be a command-line option… for reasons that escape me right
now.  :-)  But anyway, I thought we’d be in the same situation here.

Hmm I see.  The way I saw it, kexec loading is a bonus that doesn’t cost
much, which is why it’s opt-out.  It didn’t occur to me that one would
really want to control that to the level you describe.
