+  and fd_is_mount_point()
+
+* make use of new loopback setup ioctl to setup loopback devices in one atomic

+* nspawn: move "incoming mount" directory to /run/host, move "inaccessible"
+  nodes to /run/host, move notify socket (for sd_notify() between payload and

+* cryptsetup: if keyfile specified in crypttab is AF_UNIX socket, connect to it
+  and read from it (like we do elsewhere with READ_FULL_FILE_CONNECT_SOCKET)
+
+* repart: support setting up dm-integrity with HMAC
+
+* add /etc/integritytab, to support dm-integrity setups. In particular those
+  with HMAC as hash function, so that we can have a protected /home without
+  encryption (leaving encryption to the individual dirs/homed).
+
+* complement root=, rootflags=, rootfstype= with rootsubdir= which allows
+  mounting a subdir of the root fs as actual root. This can be used as
+  fstype-agnostic version of btrfs' rootflags=subvol=foobar.
