+C<guestfs_mkmountpoint> and C<guestfs_rmmountpoint> are

+
+These calls are I<only> necessary in some very limited circumstances,
+mainly the case where you want to mount a mix of unrelated and/or
+read-only filesystems together.
+
+For example, live CDs often contain a \"Russian doll\" nest of
+filesystems, an ISO outer layer, with a squashfs image inside, with
+an ext2/3 image inside that.  You can unpack this as follows
+in guestfish:
+
+ add-ro Fedora-11-i686-Live.iso
+ run
+ mkmountpoint /cd
+ mkmountpoint /squash
+ mkmountpoint /ext3
+ mount /dev/sda /cd
+ mount-loop /cd/LiveOS/squashfs.img /squash
+ mount-loop /squash/LiveOS/ext3fs.img /ext3
+
+The inner filesystem is now unpacked under the /ext3 mountpoint.");
