The distinction is made based on the format of the argument. If it is an
unsigned 32 bit integer, then it is interpreted as a process id.
Otherwise it is interpreted as a file path. /proc does not need to be
mounted to use the process id interpretation. To force the
interpretation as a file-path, use a ./ prefix.
Ambiguity is generally not a good idea (especially for security
applications). It's not my decision, but I'd rather see the syntax make
it clear what the type of the parameter is supposed to be.
The syntax is based on a similar feature in iproute2:
ip link set <device> netns <pid|name>
The syntax of wg seems to generally follow the iproute2 syntax so I
tried to keep it consistent.
