+
+    makefile: correctly sed paths
+    
+    The default Makefile for tlp makes a mess with catenating `DESTDIR` to
+    everything, but then not actualy using the catenated (_ prefixed)
+    variables to sed it's `.in` files.
+    
+    This patch makes sure that it correctly sets the paths, taking `DESTDIR`
+    in account where it makes sense (e.g. /bin where we want $out/bin) but
+    not where it doesn't (/etc/tlp.conf should be just that).
+    
+    The reason DESTDIR is used at all, as opposed to the more appropriate
+    PREFIX, is covered in the nix formula, and is (also) due to the Makefile
+    being a bit "different."

+
+    tlp-sleep.service: reintroduce
+    
+    This patch reintroduces tlp-sleep as a systemd unit as opposed to a
+    systemd system-sleep hook script. This is due to the recommendation by
+    systemd itself to not use the hook scripts. As per the manual:
+    
+    > Note that scripts or binaries dropped in /usr/lib/systemd/system-sleep/
+    > are intended for local use only and should be considered hacks. If
+    > applications want to react to system suspend/hibernation and resume,
+    > they should rather use the Inhibitor interface[1].
