This keeps composites analysis happy without making the test cases (too) bloated.

This makes handling of fatal errors a lot less squirmy.

This helps indicate the exact origin and nature of the error. This eliminates generic WrapErr from container.

Programs expect /dev/shm to be a writable tmpfs.

With the new instrumentation it is now possible to run init code outside integration tests.

The container test suite has always been somewhat inadequate due to the inability of coverage tooling to reach into containers. This has become an excuse for not testing non-container code as well, which lead to the general lack of confidence when working with container code. This change aims to be one of many to address that to some extent.

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

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,

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.

This allows for more sophisticated test setup.

This restores verbose behaviour.

This further reduces noise on test failure by only passing through output of the failed test.

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.

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.

This is useful for building a filesystem hierarchy then remounting it readonly.

This allows container processes to exit gracefully.

This change also makes some parts of the test more robust.

This is more elegant and allows for much easier extension of the tests. Mountinfo is still serialised however due to libPaths nondeterminism.

This part of the interface is very unintuitive and only used for testing, even in testing it is inelegant and can be done better.

This allows slightly easier use of the vanity url. This also provides some disambiguation between low level containers and hakurei app containers.
