+dphys-swapfile (20100506-6) unstable; urgency=medium

+  * Drop fallocate.patch: swapon(8) states that fallocate-generated
+    swapfiles will not work on certain file systems and explicitly
+    recommends the use of dd as upstream does. (Closes: #913481)
+  * Declare comliance with Debian Policy 4.4.0. (No changes needed.)
+  * Bump debhelper compatibility level to 12.
+    + Replace debian/compat with a versioned b-d on debhelper-compat.
+  * Add "Pre-Depends: ${misc:Pre-Depends}" to be able to use "invoke-rc.d
+    --skip-systemd-native". Thanks Lintian!
