[Crash-utility] How does crash find booted kernel?

[Nan Xiao]

Hi Buland,

Thanks very much for your answer! After installing the right debuginfo package,
now crash works!

BTW, if possible, could you spare a little time to explain other
confusion: it seems
that I don't select whether "debug" version or not during install RHEL
7, why does it
install the "debug" version for me? Thanks!
Best Regards
Nan Xiao
