[dm-devel] Chicken and egg problem with multipath-tools

[Andrei B]

Well, that would be an idea. However, multipathd has the pidfile
hardcoded. It cannot be changed at runtime, nor can it be disabled.

I know, I could compile it with a different hardcoded path, but that's
really a bad idea, because then if multipathd were to be restarted
anytime later after boot, it would then fail because of the same reason.
