Arg. Looks like namerefs were only added in bash 4.3. Annoying. The
fix looks something like this, but it's so ugly and bothers me:

diff --git a/src/tools/wg-quick.bash b/src/tools/wg-quick.bash
index 6edcd3a..5325f9d 100755
--- a/src/tools/wg-quick.bash
+++ b/src/tools/wg-quick.bash

 read_bool() {
-	local -n out="$1"
 	case "$2" in
-	true) out=1 ;;
-	false) out=0 ;;
+	true) eval "$1=1" ;;
+	false) eval "$1=0" ;;
 	*) die "\`$2' is neither true nor false"
 	esac
 }


Not sure whether or not I'll merge it yet.
