This function returns a C truth value on success or -1 on error.
+=head2 guestfs_get_e2label
+
+ char *guestfs_get_e2label (guestfs_h *handle,
+ const char *device);
+
+This returns the ext2/3/4 filesystem label of the filesystem on
+C<device>.
+
+This function returns a string, or NULL on error.

+
+=head2 guestfs_get_e2uuid

=head2 guestfs_get_path
const char *guestfs_get_path (guestfs_h *handle);
B<This command is dangerous. Without careful use you
can easily destroy all your data>.
+=head2 guestfs_lvremove
+
+ int guestfs_lvremove (guestfs_h *handle,
+ const char *device);
+
+Remove an LVM logical volume C<device>, where C<device> is
+the path to the LV, such as C</dev/VG/LV>.
+
+You can also remove all LVs in a volume group by specifying
+the VG name, C</dev/VG>.
+
+This function returns 0 on success or -1 on error.

=head2 guestfs_lvs
char **guestfs_lvs (guestfs_h *handle);
This function returns 0 on success or -1 on error.
+=head2 guestfs_pvremove
+
+ int guestfs_pvremove (guestfs_h *handle,
+ const char *device);
+
+This wipes a physical volume C<device> so that LVM will no longer
+recognise it.
+
+The implementation uses the C<pvremove> command which refuses to
+wipe physical volumes that contain any volume groups, so you have
+to remove those first.
+
+This function returns 0 on success or -1 on error.

=head2 guestfs_pvs
char **guestfs_pvs (guestfs_h *handle);
This function returns 0 on success or -1 on error.
+=head2 guestfs_set_e2label
+
+ int guestfs_set_e2label (guestfs_h *handle,
+ const char *device,
+ const char *label);
+
+This sets the ext2/3/4 filesystem label of the filesystem on
+C<device> to C<label>. Filesystem labels are limited to
+16 characters.
+
+You can use either C<guestfs_tune2fs_l> or C<guestfs_get_e2label>
+to return the existing label on a filesystem.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_set_e2uuid
+
+ int guestfs_set_e2uuid (guestfs_h *handle,
+ const char *device,
+ const char *uuid);
+
+This sets the ext2/3/4 filesystem UUID of the filesystem on
+C<device> to C<uuid>. The format of the UUID and alternatives
+such as C<clear>, C<random> and C<time> are described in the
+L<tune2fs(8)> manpage.
+
+You can use either C<guestfs_tune2fs_l> or C<guestfs_get_e2uuid>
+to return the existing UUID of a filesystem.
+
+This function returns 0 on success or -1 on error.

+This returns the contents of the ext2, ext3 or ext4 filesystem
+superblock on C<device>.

This function returns 0 on success or -1 on error.
+=head2 guestfs_vgremove
+
+ int guestfs_vgremove (guestfs_h *handle,

+
+Remove an LVM volume group C<vgname>, (for example C<VG>).
+
+This also forcibly removes all logical volumes in the volume
