+Subject: [PATCH] xflock4: Do not override PATH with hardcoded value.
+
+The PATH "/bin:/usr/bin" may not be a valid search path on the user's
+machine.  The screen locking program may be in /usr/local/bin or
+elsewhere.  Distros that do not conform to the FHS, such as GuixSD and
+NixOS, will not have their executables in either location.  Thus, we
+simply leave PATH alone.
