Jason A. Donenfeld ffcc09358e wg-quick: darwin: prefer system paths for tools
The only things wg-quick(8) needs from Homebrew are bash(1) and wg(8).
Other than that, it's explicitly coded against the native system
utilities. Since wg-quick(8) and bash(1) are invoked in auto_su by their
full absolute path (via $SELF and $BASH, respectively), we can simply
set the $PATH to be prefixed by the default system binary paths. This
way, if users install tools that conflict with system tools -- such as
GNU coreutils -- we won't accidently call those.

It's unclear why it was like this in the first place, but it apparently

Jason A. Donenfeld 2044bb026d wg-quick: android: delay setting users until end
`ndc users add` eventually invokes SOCK_DESTROY on user sockets, causing
them to reconnect. By delaying this until after routes are set, we
ensure that the sockets reconnect using the tunnel, rather than the old
route.

Jason A. Donenfeld 206e8f08e2 wg-quick: darwin: set DNS servers after delay on route change
This works around a race condition in macOS's network daemons, while
also adding one in the form of possibly calling kill -ALRM on a stale
PID; unfortunately bash can't wait from a trap.
