+This call allows you to adjust various filesystem parameters of
+an ext2/ext3/ext4 filesystem called C<device>.
+
+The optional parameters are:
+
+=over 4
+
+=item C<force>
+
+Force tune2fs to complete the operation even in the face of errors.
+This is the same as the tune2fs C<-f> option.
+
+=item C<maxmountcount>
+
+Set the number of mounts after which the filesystem is checked
+by L<e2fsck(8)>.  If this is C<0> then the number of mounts is
+disregarded.  This is the same as the tune2fs C<-c> option.
+
+=item C<mountcount>
+
+Set the number of times the filesystem has been mounted.
+This is the same as the tune2fs C<-C> option.
+
+=item C<errorbehavior>
+
+Change the behavior of the kernel code when errors are detected.
+Possible values currently are: C<continue>, C<remount-ro>, C<panic>.
+In practice these options don't really make any difference,
+particularly for write errors.
+
+This is the same as the tune2fs C<-e> option.
+
+=item C<group>
+
+Set the group which can use reserved filesystem blocks.
+This is the same as the tune2fs C<-g> option except that it
+can only be specified as a number.
+
+=item C<intervalbetweenchecks>
+
+Adjust the maximal time between two filesystem checks
+(in seconds).  If the option is passed as C<0> then
+time-dependent checking is disabled.
+
+This is the same as the tune2fs C<-i> option.
+
+=item C<reservedblockspercentage>
+
+Set the percentage of the filesystem which may only be allocated
+by privileged processes.
+This is the same as the tune2fs C<-m> option.
+
+=item C<lastmounteddirectory>
+
+Set the last mounted directory.
+This is the same as the tune2fs C<-M> option.
+
+=item C<reservedblockscount>
+Set the number of reserved filesystem blocks.
+This is the same as the tune2fs C<-r> option.
+
+=item C<user>
+
+Set the user who can use the reserved filesystem blocks.
+This is the same as the tune2fs C<-u> option except that it
+can only be specified as a number.
+
+=back
+
+To get the current values of filesystem parameters, see
+C<guestfs_tune2fs_l>.  For precise details of how tune2fs
+works, see the L<tune2fs(8)> man page.");
