How do you know that a server was "started on that port", and that
if failed specifically because it failed to bind?

There is no standardized (Unix) way to mark that a service wants to
listen on a specific port, or that it failed because a specific port
was bound by some other process.

There are various classical *inetd* daemons, and modern systemd.socket,
that listen *instead* of some service. Then they can manage the port
resources and perhaps do something intelligent about them.

It should be quite easy to patch otopi's services.state to run something
if start fails, e.g. 'ss -anp' or whatever you want.

It should even be not-too-hard to do this in a self-contained plugin,
so can be part of otopi-debug-plugins.

If we decide that something needs to be implemented by each server,
perhaps "something" should be to be controlled by a systemd.socket unit.
Didn't try, though, to see what this actually buys us.

Pushed now:

https://gerrit.ovirt.org/84699 core: Name TRANSACTION_INIT
https://gerrit.ovirt.org/84700 plugins: debug: Add debug_failure
https://gerrit.ovirt.org/84701 automation: Test failure

Will merge soon, if all goes well.

Feel free to open BZ for other things discussed above, if relevant.
