-<li><b>Ext4fs</b>—Stefan Agner modified the rEFIt/rEFInd ext2fs
- driver so that it could handle ext4fs. I'm including this as a separate
- driver from the ext2fs driver, although the ext4fs version can handle
- ext2fs and ext3fs, too. (I may eventually retire the original ext2fs
- driver, but I want to be conservative about this in case there's an
- undiscovered problem with the new driver.) This driver has some
- limitations. Most notably, for various reasons it maxes out at 16TiB
- and won't mount any ext4 filesystem that's larger than this. It also
- doesn't support the <tt>meta_bg</tt> option flag; if your filesystem
- uses this flag, this driver refuses to read it. You can learn about
