So, there has been this todo list item for a while to support a mode
where a failing service at boot would result in boot status output to be
turned on. Still not sure iof such a logic would be a good upstream
default, but certainly a good default for more technically-minded
distros such as Debian.

So maybe something like this: In addition to the boolean values for
systemd.show_status= on the kernel cmdline (or ShowStatus= in
system.conf), we'd add a third value called "auto". If that is set
we'd boot up without any status output, until either at least one
service failed, or at least one job reaches its timeout half-way. When
that point is reached we'c continue the entire rest of the boot with
status output enabled. And we wouldn't just turn the logging on, we'd
also explain why we turned it on in one "introductory" message: "Turning
on boot-time status output because of service failure:", or "Turning
on boot-time status output because of nearing job timeout:" or something
like that.

I'd be happy to see a patch like that merged.
