Thanks, that pretty much matches my thinking. There's a lot of
potential complexity here.
Another way to approach this would be to specify addresses (endpoints)
that must be reachable (for some definition of reachable: ICMP ping,
TCP open, etc.), and then the monitoring tool would run an initial s
I think it's better to use a custom tool. RequiresMountsFor relies on
knowing the exact mount points from the beginning and just waiting for them
to be done – but that might not exactly match networking, where you might
have two /24 routes today and a /23 tomorrow, so you can't exactly
predefine th
I've got a number of systems that use BIRD to learn the routes
available on their networks, and as a result some services on those
systems attempt to start up before the routes have been learned. If
those services attempt to make network connections (even just DNS
queries), they will fail, and that
