+Subject: udev: re-enable mount propagation for udevd
+
+Upstream-Status: Backport [http://http.debian.net/debian/pool/main/s/systemd/systemd_215-17+deb8u4.debian.tar.xz]
+
+laptop-mode-tools remounts file systems from within a udev rule to apply
+certain mount options. With MountFlags=slave, those mounts then become private
+to the systemd-udevd namespace and are no longer accessible from outside the
+namespace.
+While the root cause is the broken behaviour of laptop-mode-tools, with mount
+propagation turned off, this can result in a read-only root file system.
+Therefore revert the relevant parts from commit
+c2c13f2df42e0691aecabe3979ea81cd7faa35c7 to re-enable mount propagation for
+udevd.
+
+Once affected packages have been fixed, this patch should be dropped
+again.
+
+Closes: #762018
