It's helpful to understand that any child process started by a parent
process always inherits the environment of the parent.  The cwd
(current working directory) is part of that environment.  Any other
environment variables that are exported, such as PATH, etc.. are also
part of that environment.

So yes, the daemon process will start in the same directory that the
script is currently in, and assuming the daemon does not 'cd' by
itself, it should continue to run with that directory as the cwd.
