Interesting. Do you have extents enabled in the filesystem? Mine does: |
| 25 |
|
| 26 |
# tune2fs -l /dev/sda4 | grep features |
| 27 |
Filesystem features: has_journal ext_attr resize_inode dir_index |
| 28 |
filetype needs_recovery extent sparse_super large_file uninit_bg |
| 29 |
|

I was under the impression that GRUB legacy could not read ext4 |
| 31 |
filesystems with extents enabled; that was the primary reason I |
| 32 |
migrated to GRUB2. I believe there is a patch for GRUB legacy which |
| 33 |
adds ext4+extents support, but I don't think Gentoo applies it. |
| 34 |
|
| 35 |
If GRUB legacy supports ext4 from upstream, then it's a new feature |
| 36 |
(or certainly, I hadn't heard about it until now). |
