The privileged user is identifier to hakurei through its hsu userid. Using the kernel uid here makes little sense and is a leftover design choice from before hsu was implemented.
Closes #7.

There is no reason to give the home directory special treatment, as this behaviour can be quite confusing. The home directory also does not necessarily require its own mount point, it could be provided by a parent or simply be ephemeral.

This exposes the BindEnsure flag of BindMountOp.

This is used for ensuring persistent data directories specific to the container.

This shortens the representation of most common use cases and generally improves readability.

Symlinks do not require special treatment, and doing this allows placing links in order.

The Type method no longer exists on the interface. Update doc comments to reflect that.

This no longer needs special treatment since it can be specified as a generic filesystem entry.

This generalises the special field allowing any special behaviour to be matched from target.

This allows any fstype supported by hst to be directly mounted on sysroot. A special case in internal/app applies the matching entry early and excludes it from path hiding.
Closes #5.

This allows autoroot to be configured via Filesystem.

Turns out testing.T does not like being called in defer.

This field has been a noop for a long time. Remove it to prevent further confusion.

This is for supporting overlay mounts for autoroot.

This used to be entirely done via integration tests, with almost no hope of error injection and coverage profile. These tests significantly increase confidence of future work in this area.

This allows instrumentation of calls from goroutine without relying on finalizers.

This reduces the size of []kexpect in the test suite.

Scheduler nondeterminism cannot be accounted for, so do this instead.
There should not be any performance penalty as these calls are optimised out for direct.

The file is very difficult to stub. Pass fd instead as it is the value that is actually useful.

This degrades test performance if not stubbed out.

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

This allows path and mount functions to be instrumented.

This allows tests to stub all kernel behaviour, enabling measurement of all function call arguments and error injection.

Same problem as autoroot, never updated the checks after integrating Absolute.

This will never return true otherwise unless the equivalent paths happen to be interned by the caller.

This is unreachable, but nice to have just in case.

This is only a nice to have feature as the init process has no additional privileges and the monitor process was never reachable anyway.

These can quite easily be checked within the framework. The scanner fault injection might require updating at some point if the implementation changes.
