    SubjectRe: Linux 2.2.18pre1
    attention everyone,

    the assumption that people who use raid or nfs always use a patched kernel
    is not true.

    in many cases it is not trivial to find the newest patches and tools to go
    with them (documentation limitations) and in other cases the stock stuff
    seems to work so people don't realize there is a reason to upgrade.
