And I whole-heartedly believe this is something that fundamentally needs
to be addressed in systemd, not in the kernel.
This aproach is actually introducing a user-visible regressions. Look, for
example, exec() never times out. Therefore if your system is on its knees,
heavily overloaded (or completely broken), you are likely to be able to
`reboot' it, because exec("/sbin/reboot") ultimately succeeds.
But with all the timeouts, dbus, "Failed to issue method call: Did
not receive a reply" messages, this is getting close to impossible.
