@item @code{create-mount-point?} (default: @code{#f})
When true, the mount point is created if it does not exist yet.
+@item @code{dependencies} (default: @code{'()})
+This is a list of @code{<file-system>} objects representing file systems
+that must be mounted before (and unmounted after) this one.

+As an example, consider a hierarchy of mounts: @file{/sys/fs/cgroup} is
+a dependency of @file{/sys/fs/cgroup/cpu} and
+@file{/sys/fs/cgroup/memory}.
