Also, systemd comes with a timeout, after which it kills the app anyways, so I think you can surely configure that 90s timeout to be something like 5s or so, which then is much faster.

But as you wrote, If someone really cares, they would fix it.

PS: But what usually gets me about these 90s waits whenever I get them is that the message does not say which thing (unit, etc) is the issue. THAT is something worth criticising.
