I think you are right.... I discussed it with alexander today and I propose
that installation of linux_base should set (or tell user to set) the osrelease
to the version whicih is the given linux_base shipped with on default.

fc4 ships with 2.6.11 kenrel and we force it to use 2.4.2 no wonder it doesnt
work as expected

thnx for the info
