Hi Tomas,

(+ Dariqq since we briefly discussed it on IRC yesterday.)

Tomas Volf <~@wolfsden.cz> skribis:

> wait time), the initial messages are all together:

Indeed.  As Dariqq found out, the problem was that we’d mark one-short
services in ‘%one-shot-services-started’ as soon as we’ve started them,
effectively acting as if “started” were synonymous with “running”.

This is fixed with 550c0370985022c5c90a7b477a5e0b84f6faf5d7.

Let me know if you find anything fishy!

Thanks,
Ludo’.
