Hello,
finally I have some positive news for all of you!
In the latest Turris OS, which is 3.9.1 you can start/stop/restart container whatever you want.

We’re working on it.
and about ArchLinux we looked at it and it is installed just fine. See this respond:
btw there was no reason to create another same thread. So I’m closing the other one. Continue, please here.
