stephen/smooge!
thanks for the reply...
not a school project, a machine is having intermittent crashes, and i want
to know more detailed information.. so i need to have a debug kernel in
order to keep testing.
the issue with the kernel-debuginfo, is that it appears to essentially be
the OS with the debug/symbolic information. you apparently don't actually
run the rpm/app after it's installed.. but it gives the 'crash' app the
ability to match/resolve symbolic information in the event of a crash/hang
within the OS....
you supplied me with info that i had eventually found after hours of
searching... i had created debug kernel scenarios years ago, but needed to
be sure things hadn't changed...
thanks

I am guessing this is for some school project...
The debug kernel you mentioned was only upstream in 2.1. The 'code' to
create the kernel-debug is in that spec file ONLY. Red Hat changed its
way of doing things and put all the debugging information in
-debuginfo packages sometime during the Fedora packages (FC3 was
stabilized into RHEL-4.. so Centos-4 would be your best bet to
creating all the debuginfo pacakges.)
In your 'build' system you will want to make sure that the rpmmacros
files do not have
%debug_package %{nil}
so that the automatic debug packages are created.
What google will tell you:
