+=head2 guestfs_debug
+
+ char *guestfs_debug (guestfs_h *handle,
+ const char *subcmd,
+ char * const* const extraargs);
+
+The C<guestfs_debug> command exposes some internals of
+C<guestfsd> (the guestfs daemon) that runs inside the
+qemu subprocess.
+
+There is no comprehensive help for this command. You have
+to look at the file C<daemon/debug.c> in the libguestfs source
+to find out what you can do.
+
+This function returns a string, or NULL on error.
+I<The caller must free the returned string after use>.

int guestfs_download (guestfs_h *handle,
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>.

+I<The caller must free the returned string after use>.
+
+=head2 guestfs_get_e2uuid
+
+ char *guestfs_get_e2uuid (guestfs_h *handle,

=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_mount_options
+
+ int guestfs_mount_options (guestfs_h *handle,
+ const char *options,
+ const char *device,
+ const char *mountpoint);
+
+This is the same as the C<guestfs_mount> command, but it
+allows you to set the mount options as for the
+L<mount(8)> I<-o> flag.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_mount_ro
+
+ int guestfs_mount_ro (guestfs_h *handle,
+ const char *device,
+ const char *mountpoint);
+
+This is the same as the C<guestfs_mount> command, but it
+mounts the filesystem with the read-only (I<-o ro>) flag.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_mount_vfs
+
+ int guestfs_mount_vfs (guestfs_h *handle,
+ const char *options,
+ const char *vfstype,
+ const char *device,
+ const char *mountpoint);
+
+This is the same as the C<guestfs_mount> command, but it
+allows you to set both the mount options and the vfstype
+as for the L<mount(8)> I<-o> and I<-t> flags.
+
+This function returns 0 on success or -1 on error.

=head2 guestfs_mounts
char **guestfs_mounts (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 returns the contents of the ext2 or ext3 filesystem superblock
-on C<device>.
+This returns the contents of the ext2, ext3 or ext4 filesystem
