+=item $partitions = $h->sfdisk_disk_geometry ($device);
+
+This displays the disk geometry of C<device> read from the
+partition table. Especially in the case where the underlying
+block device has been resized, this can be different from the
+kernel's idea of the geometry (see C<$h-E<gt>sfdisk_kernel_geometry>).
+
+The result is in human-readable format, and not designed to
+be parsed.
+
+=item $partitions = $h->sfdisk_kernel_geometry ($device);
+
+This displays the kernel's idea of the geometry of C<device>.
+
+The result is in human-readable format, and not designed to
+be parsed.
+
+=item $partitions = $h->sfdisk_l ($device);
+
+This displays the partition table on C<device>, in the
+human-readable output of the L<sfdisk(8)> command. It is
+not intended to be parsed.
+
+=item $output = $h->sh ($command);
+
+This call runs a command from the guest filesystem via the
+guest's C</bin/sh>.
+
+This is like C<$h-E<gt>command>, but passes the command to:
+
+ /bin/sh -c "command"
+
+Depending on the guest's shell, this usually results in
+wildcards being expanded, shell expressions being interpolated
+and so on.
+
+All the provisos about C<$h-E<gt>command> apply to this call.
+
+=item @lines = $h->sh_lines ($command);
+
+This is the same as C<$h-E<gt>sh>, but splits the result
+into a list of lines.
+
+See also: C<$h-E<gt>command_lines>
+
+=item $h->sleep ($secs);
+
+Sleep for C<secs> seconds.
