This function returns 0 on success or -1 on error.
+=head2 guestfs_e2fsck_f
+
+ int guestfs_e2fsck_f (guestfs_h *handle,
+ const char *device);
+
+This runs C<e2fsck -p -f device>, ie. runs the ext2/ext3
+filesystem checker on C<device>, noninteractively (C<-p>),
+even if the filesystem appears to be clean (C<-f>).
+
+This command is only needed because of C<guestfs_resize2fs>
+(q.v.). Normally you should use C<guestfs_fsck>.
+
+This function returns 0 on success or -1 on error.
+
=head2 guestfs_end_busy
int guestfs_end_busy (guestfs_h *handle);
This function returns a string, or NULL on error.
I<The caller must free the returned string after use>.
+=head2 guestfs_find
+
+ char **guestfs_find (guestfs_h *handle,
+ const char *directory);
+
+This command lists out all files and directories, recursively,
+starting at C<directory>. It is essentially equivalent to
+running the shell command C<find directory -print> but some
+post-processing happens on the output, described below.
+
+This returns a list of strings I<without any prefix>. Thus
+if the directory structure was:
+
+ /tmp/a
+ /tmp/b
+ /tmp/c/d
+
+then the returned list from C<guestfs_find> C</tmp> would be
+4 elements:
+
+ a
+ b
+ c
+ c/d
+
+If C<directory> is not a directory, then this command returns
+an error.
+
+The returned list is sorted.
+
+This function returns a NULL-terminated array of strings
+(like L<environ(3)>), or NULL if there was an error.
+I<The caller must free the strings and the array after use>.
+
=head2 guestfs_fsck
int guestfs_fsck (guestfs_h *handle,
This function returns 0 on success or -1 on error.
+=head2 guestfs_lvresize
+
+ int guestfs_lvresize (guestfs_h *handle,
+ const char *device,
+ int mbytes);
+
+This resizes (expands or shrinks) an existing LVM logical
+volume to C<mbytes>. When reducing, data in the reduced part
+is lost.
+
+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_pvresize
+
+ int guestfs_pvresize (guestfs_h *handle,
+ const char *device);
+
+This resizes (expands or shrinks) an existing LVM physical
+volume to match the new size of the underlying device.
+
+This function returns 0 on success or -1 on error.
+
=head2 guestfs_pvs
char **guestfs_pvs (guestfs_h *handle);
(like L<environ(3)>), or NULL if there was an error.
I<The caller must free the strings and the array after use>.
+=head2 guestfs_resize2fs
+
+ int guestfs_resize2fs (guestfs_h *handle,
+ const char *device);
+
+This resizes an ext2 or ext3 filesystem to match the size of
+the underlying device.
+
+I<Note:> It is sometimes required that you run C<guestfs_e2fsck_f>
+on the C<device> before calling this command. For unknown reasons
+C<resize2fs> sometimes gives an error about this and sometimes not.
+In any case, it is always safe to call C<guestfs_e2fsck_f> before
+calling this function.
+
+This function returns 0 on success or -1 on error.
+
=head2 guestfs_rm
int guestfs_rm (guestfs_h *handle,
pass C<lines> as a single element list, when the single element being
the string C<,> (comma).
+See also: C<guestfs_sfdisk_l>, C<guestfs_sfdisk_N>
+
This function returns 0 on success or -1 on error.
B<This command is dangerous. Without careful use you
can easily destroy all your data>.
+=head2 guestfs_sfdisk_N
+
+ int guestfs_sfdisk_N (guestfs_h *handle,
+ const char *device,
+ int n,
+ int cyls,
+ int heads,
+ int sectors,
+ const char *line);
+
+This runs L<sfdisk(8)> option to modify just the single
+partition C<n> (note: C<n> counts from 1).
+
+For other parameters, see C<guestfs_sfdisk>. You should usually
+pass C<0> for the cyls/heads/sectors parameters.
+
+This function returns 0 on success or -1 on error.

+B<This command is dangerous. Without careful use you
+can easily destroy all your data>.
+
+=head2 guestfs_sfdisk_disk_geometry
+
+ char *guestfs_sfdisk_disk_geometry (guestfs_h *handle,
+ const char *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<guestfs_sfdisk_kernel_geometry>).
+
+The result is in human-readable format, and not designed to
+be parsed.
+
+This function returns a string, or NULL on error.
+I<The caller must free the returned string after use>.
+
+=head2 guestfs_sfdisk_kernel_geometry
+
+ char *guestfs_sfdisk_kernel_geometry (guestfs_h *handle,
+ const char *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.
+
+This function returns a string, or NULL on error.
+I<The caller must free the returned string after use>.
+
+=head2 guestfs_sfdisk_l
+
+ char *guestfs_sfdisk_l (guestfs_h *handle,
+ const char *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.
+
+This function returns a string, or NULL on error.
+I<The caller must free the returned string after use>.

=head2 guestfs_stat
struct guestfs_stat *guestfs_stat (guestfs_h *handle,
This function returns 0 on success or -1 on error.
+=head2 guestfs_vg_activate
+
+ int guestfs_vg_activate (guestfs_h *handle,
+ int activate,
+ char * const* const volgroups);
+
+This command activates or (if C<activate> is false) deactivates
+all logical volumes in the listed volume groups C<volgroups>.
+If activated, then they are made known to the
+kernel, ie. they appear as C</dev/mapper> devices. If deactivated,
+then those devices disappear.
+
+This command is the same as running C<vgchange -a y|n volgroups...>
+
+Note that if C<volgroups> is an empty list then B<all> volume groups
+are activated or deactivated.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_vg_activate_all
+
+ int guestfs_vg_activate_all (guestfs_h *handle,
+ int activate);
+
+This command activates or (if C<activate> is false) deactivates
+all logical volumes in all volume groups.
+If activated, then they are made known to the
+kernel, ie. they appear as C</dev/mapper> devices. If deactivated,
