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.

Having the bit field value here (in decimal, no less) is unfriendly to text editors. Use a bunch of booleans here to improve ease of use.

This needs to be done from the Go side eventually anyway to integrate the signal forwarding behaviour now supported by the container package.

This process runs outside the application container's pid namespace, so it is a good idea to check whether its lifecycle becomes decoupled from the application.

The config struct more or less "grew" to what it is today. This change moves things around to make more sense and fixes nonsensical comments describing obsolete behaviour.

This ensures a signal gets delivered to the process instead of relying on parent death behaviour.
SIGCONT was chosen as it is the only signal an unprivileged process is allowed to send to processes with different credentials.
A custom signal handler is installed because the Go runtime does not expose signal information other than which signal was received, and shim must check pid to ensure reasonable behaviour.

This removes the unnecessary creation and destruction of share paths when none of the enablements making use of them are set.

By default test vm commands run as root, this causes buildFHSEnv bwrap to cover some parts of /proc, making it impossible to mount proc in a mount namespace created under it. Running as a regular user gets around this issue.
