container/ops: move Op type to init file2025-08-19T16:11:24ZOphestracat@gensokyo.uk2025-08-19T16:11:24Zurn:sha1:339e4080dce73d372f6111773066b9c84308b6b7
This helps with the eventual separation of all setup ops into individual files.

container: enforce nonrepeatable autoetc and autoroot2025-08-16T16:43:11ZOphestracat@gensokyo.uk2025-08-16T16:43:11Zurn:sha1:9c1a5d43bad802aa0ad717ea603c51f7b0408cdd
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.

container: allow additional state between ops2025-08-16T16:32:07ZOphestracat@gensokyo.uk2025-08-16T16:29:54Zurn:sha1:8aa65f28c68815db9dd1f246ee2656759574c3bb
This is useful for ops that need to be aware of previous instances of themselves.

This is simultaneously more efficient and less error-prone. This change caused minor API changes in multiple other packages.

container/ops: implement overlay op2025-08-07T16:54:48ZOphestracat@gensokyo.uk2025-08-07T16:50:38Zurn:sha1:acffa76812eb2972f2478b55fe2ba1e0ae8fa41d
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.

container/path: fhs path constants2025-08-03T12:16:45ZOphestracat@gensokyo.uk2025-08-03T11:46:41Zurn:sha1:c6be82bcf91fc4b6e61d9df40213e80367addbd8
This increases readability since this can help disambiguate absolute paths from similarly named path segments.

container/ops: mount dev readonly2025-08-03T10:18:53ZOphestracat@gensokyo.uk2025-08-03T10:18:53Zurn:sha1:38245559dca0833dc078b982d59490eee53e168c
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.

container/ops: merge mqueue and dev Ops2025-08-03T10:13:46ZOphestracat@gensokyo.uk2025-08-03T09:34:55Zurn:sha1:7b416d47dcb830aab5daa432cf79af5f8bbacaef
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.
