um,
so let me ask another question.
should a disk that was fdisk/formatted on an earlier kernel (i.e.
before this change, for example a 2.0.26 kernel) work _as is_ under
the new kernels, or do I need to NFS copy my 100 gigabytes of data
from one system to the other ?
(hint: an existing 1024 byte sector disc, works fine under 2.0.36,
at present cannot be mounted on 2.2.5 - complaints of corrupted superblock,
or some such nonsense.)
