    I agree it's useful. I just don't think the user manual is the appropriate place for it
and think the release notes are better, since they are tied to the characteristics of a specific
release, and are far less likely to be stale.
    
    This information is most useful to people building, integrating, and packaging Accumulo,
and the information in the user manual should still apply to their builds (without modification)
as it does to the ones we've tested. If this is contained in the user manual, then they'll
have to modify the user manual if they want it to be accurate for their environment.
    
    For example... for the Fedora packaging, any references in the user manual to any version
of our dependencies which aren't the versions packaged in Fedora, simply wouldn't apply.
