This is a more reliable form of pathname to self and also cheaper than os.Executable.

This change removes inconsistencies collected over time in this package.

This is thread-directed so cannot be done externally. The glibc wrapper exposes this behaviour so most multithreaded programs using this is straight up incorrect.

This enables loopback networking when owning the net namespace.

This is required for the typical daemonise use case.

While fd created from this side always has the FD_CLOEXEC flag, the same is not true for files left open by the parent. This change prevents those files from leaking into the container.

Seccomp lookup tables are going to be relocated here, and PNR constants.

Should have done this when relocating this from container. Now is a good time to rename it before v0.3.x.

This increases flexibility of how caller wants to handle the I/O. Also makes it no longer rely on finalizer.

The SIGTERM signal is delivered in many other cases and can lead to strange behaviour. The unconditional resume of the logger also causes strange behaviour in the cancellation forwarding path. This change also passes through additional signals.

This package will also hold syscall lookup tables for seccomp.

This package is quite useful. This change allows it to be imported without importing container.

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.

This allows some LSM setup in the parent.

This allows setup that relies on per-thread state like securebits and landlock, from the parent side.

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,

This increases readability since this can help disambiguate absolute paths from similarly named path segments.

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.
