I'm building under ubuntu 12.04 installed on a VirtualBox. There are
two partitions, /dev/sda1 for the ubuntu build system, /dev/sda5 for the
target lfs. Both of them are formatted ext4.
debugfs -R feature /dev/sda5
reported extra features:
extent
flex_bg
huge_file
uninit_bg
dir_nlink
extra_isize
Reluctant to build a whole new e2fsprogs, I consulted /etc/mke2fs.conf,
and it appeared that, at least so far as the ubuntu team is concerned,
the features above differentiate an ext4 from an ext3 filesystem.
So I reformatted /dev/sda5 as an ext3. 'debugfs' now reports a leaner
feature set for /dev/sda5. It satisfies the constraints of the section
2.3 note.
Could I have gone ahead with the ext4 partition and its extra features?
Bruce said, back in February, that ext3/4 shouldn't make a difference.
But doesn't the section 2.3 note imply that it *does* (or at least
*might* ) make a difference?
