There is no way to have machinectl pass part of its argv to the child, and formatting the string for a shell is highly error-prone and complex, so the argv slice is encoded and passed to a launcher process launched by machinectl which then calls execve(2) to start the final process.

According to manpage acl_get_qualifier(3) the void * returned by this function could be allocated on the heap.

Since we link libxcb as well now this is needed in the dev shell for it to build properly without impure.

Even though many pure Go libxcb implementations exist, it is at least as complex and unreadable as libxcb, if not more. Since well known libraries like SDL, qt and gtk uses libxcb, and they somehow understand how to use it, I can only assume these people have read enough code to make sure it's correct enough. Call it wishful thinking. I don't care anymore.

Manpage provided by systemd states that the sd_booted function internally "checks whether the directory /run/systemd/system/ exists", as well as that "a simple check like this can also be implemented trivially in shell or any other language". This implies the behaviour of this function can be expected to be stable.

The library is simple and should be easy to port to Go, however correctness matters more in this case and overhead from cgo is negligible for our usage scenario.

Copy all flags from upstream. The machinectl flag is dropped as it does nothing. the flag package is used to reduce complexity since we do not care about compatibility with upstream.
