I guess this depends very much on what the container image does. Doing basic Unix/Posix stuff in an application container shouldn't be that much work. But until systemd or something else very Linux-specific runs in a system container sounds like a huge amount of work.
- trasz 4y agoFrom my experience there are few examples of software that’s both Linux-specific and actually useful. As for systemd - which container mechanisms depend on it?
- usr1106 4y agoIt's the other way round. systemd depends on functionality offered by the Linux kernel like e.g. cgroups.
- trasz 4y agoOkay, so what? The reason for missing support for those mechanisms is mostly the lack of need. And this goes deep in the Linux land, for example the Linux-specific signalfd(2) system call is pretty much completely unused - except for systemd.
