cat 9c1a5d43ba container: enforce nonrepeatable autoetc and autoroot 
These keep track of some internal state, and they don't make sense to have multiple instances of anyway, so instead of dealing with that, just make them nonrepetable.

cat 8aa65f28c6 container: allow additional state between ops 
This is useful for ops that need to be aware of previous instances of themselves.

cat 02271583fb container: remove PATH lookup behaviour 
This is way higher level than the container package and does not even work unless every path is mounted in the exact same location.

This behaviour causes nothing but confusion and problems,

cat acffa76812 container/ops: implement overlay op 
There are significant limitations to using the overlay mount, and the implementation in the kernel is quite quirky. For now the Op is quite robust, however a higher level interface for it has not been decided yet.

cat 38245559dc container/ops: mount dev readonly 
There is usually no good reason to write to /dev. This however doesn't work in internal/app because FilesystemConfig supplied by ContainerConfig might add entries to /dev, so internal/app follows DevWritable with Remount instead.

cat 7b416d47dc container/ops: merge mqueue and dev Ops 
There is no reason to mount mqueue anywhere else, and these Ops usually follow each other. This change merges them. This helps decrease IPC overhead and also enables mounting dev readonly.
