That’s very true. Luckily, for me at least, I very rarely rest5art my computer, when I’m in front of it. Only for updates. So I didn’t notice it for that.
I only noticed it with shutdown. And I don’t hang around to wait for my PC to shutdown. I click shutdown and leave it be. So it doesn’t really other me.
But for what it’'s worth, it’s not a Manjaro-bug. It’s systemd I think. If you search Google you’ll find the problem isn’t localized to Manjaro, but appears in, at least, 2 other distributions as well.
