Right that's exactly the kind of info I am talking about kernel > foo +
CONFIG_BAR set etc.

No it's generally not a surprise for people/users that read docs :)

The users I am trying to protect are:

1) packagers in distributions != Fedora
2) people that builds backports of our packages on RHEL5 or Centos 5 or
whatever...

It might also be an option to extend gfs2-utils configure.ac to check
for those versions at build time. It might be an excessive precaution,
but it could also save some headaches.. no strong opinion here.. barely
a suggestion.
