[systemd-devel] sshd.service fails on boot when primary listener is a bridge (br0) instead of real interface (eth0). What dependency is needed?

Well, I mean, the entire logic of delaying the boot for external
conditions is already pretty wrong. If you want to fix this, then
make sure sshd doesn't need the network to be up to start up (for
example by using socket activation, or by using IP_FREEBIND). 

But I mean, what you are asking for is basically delaying boot
completion indefinitely. I doubt that that'd be a good mechanism to
have...

Yes, sorry for the typos!
