A lot of complaints I’ve seen is that it’s bloated - it’s not only a system manager but also has a DNS relay, network manager, container manager, and so on.
That said, codifying service startup and managing them with cgroups is IMO MUCH better than init scripts that think running killall apache
is a good way to stop a service.
As far as I know, no one has demonstrated that they can successfully run their own instance and have it integrated with the main Bluesky infrastructure as easily as the spec authors have claimed.
Until that happens, all the talk about federation and open standards is just that - talk.
