+Subject: namespace: make MountFlags=shared work again
+
+Since commit 0722b359342d2a9f9e0d453875624387a0ba1be2, the root mountpoint is
+unconditionnally turned to slave which breaks units that are using explicitly
+MountFlags=shared (and no other options that would implicitly require a slave
+root mountpoint).
+
+Here is a test case:
+
+  $ systemctl cat test-shared-mount-flag.service
+  # /etc/systemd/system/test-shared-mount-flag.service
+  [Service]
+  Type=simple
+  ExecStartPre=/usr/bin/mkdir -p /mnt/tmp
+  ExecStart=/bin/sh -c "/usr/bin/mount -t tmpfs -o size=10M none /mnt/tmp && sleep infinity"
+  ExecStop=-/bin/sh -c "/usr/bin/umount /mnt/tmp"
+  MountFlags=shared
+
+  $ systemctl start test-shared-mount-flag.service
+  $ findmnt /mnt/tmp
+  $
+
+Mount on /mnt/tmp is not visible from the host although MountFlags=shared was
+used.
+
+This patch fixes that and turns the root mountpoint to slave when it's really
+required.
+
