particular that the filename is not prepended to the output
(the C<-b> option).
+=head2 fsck
+
+ fsck fstype device
+
+This runs the filesystem checker (fsck) on C<device> which
+should have filesystem type C<fstype>.
+
+The returned integer is the status. See L<fsck(8)> for the
+list of status codes from C<fsck>.
+
+Notes:
+
+=over 4
+
+=item *
+
+Multiple status codes can be summed together.
+
+=item *
+
+A non-zero return code can mean "success", for example if
+errors have been corrected on the filesystem.
+
+=item *
+
+Checking or repairing NTFS volumes is not supported
+(by linux-ntfs).
+
+=back
+
+This command is entirely equivalent to running C<fsck -a -t fstype device>.

=head2 get-autosync
get-autosync
Get the autosync flag.
+=head2 get-e2label
+
+ get-e2label device
+
+This returns the ext2/3/4 filesystem label of the filesystem on
+C<device>.
+
+=head2 get-e2uuid
+
+ get-e2uuid device
+
+This returns the ext2/3/4 filesystem UUID of the filesystem on
+C<device>.

set-autosync true|false
If C<autosync> is true, this enables autosync. Libguestfs will make a
-best effort attempt to run C<sync> when the handle is closed
+best effort attempt to run C<umount-all> followed by
+C<sync> when the handle is closed
(also if the program exits without closing handles).
+This is disabled by default (except in guestfish where it is
+enabled by default).
+
+=head2 set-e2label
+
+ set-e2label device 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<tune2fs-l> or C<get-e2label>
+to return the existing label on a filesystem.
+
+=head2 set-e2uuid
+
+ set-e2uuid device 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<tune2fs-l> or C<get-e2uuid>
+to return the existing UUID of a filesystem.
+
=head2 set-path | path
set-path path
of somewhere between 2MB and 4MB. To transfer large files you should use
FTP.
+=head2 zero
+
+ zero device
+
+This command writes zeroes over the first few blocks of C<device>.
+
+How many blocks are zeroed isn't specified (but it's I<not> enough
+to securely wipe the device). It should be sufficient to remove
+any partition tables, filesystem superblocks and so on.
