+Subject: [PATCH] [NixOS] Unwrap executable name for .desktop search
+
+Why is this necessary even though -a "$0" is used in the wrapper?
+Because it's completely bypassing argv0! This looks at the executable
+file in-use according to the kernel!
+
+Wrappers cannot affect the `/proc/.../exe` symlink!

+Subject: [PATCH] [NixOS] Unwrap executable name for .desktop search
+
+Why is this necessary even though -a "$0" is used in the wrapper?
+Because it's completely bypassing argv0! This looks at the executable
+file in-use according to the kernel!
+
+Wrappers cannot affect the `/proc/.../exe` symlink!
