Agreed. But can't distro's give two SET's of RPMS: 1. kernel-xyz.rpm 2. kernel-xyz-debug.rpm
where both 1,2 are same kernels compiled w/ same config and with -g. BUT rpm [1] is a 'strip -g' output of [2].
So people run [1] on their production systems. And developers analyze core-dump from these systems using [2]. Can this be done and will it work?
Thanks in advance,
