And here is what I got:

# tune2fs -l /dev/hda6 | grep "Filesystem features"
Filesystem features:      filetype sparse_super

# tune2fs -l /dev/hda7 | grep "Filesystem features"
Filesystem features:      has_journal filetype sparse_super

For good measure, I also ran the command on /dev/hda7.  This contains
the Sarge pre-release and was installed as an .ext3 filesystem.

It looks as though the initrd complaint is valid.  And adding the
journal (by running the command from /dev/hda7) is not a problem.  I
just wanted to check that I will not break something if I do.  The
output, that "tune2fs -l" can produce, was news to me.

Thank you for pointing it out.
