Re: [Crash-utility] How does crash find booted kernel?
----- Original Message -----
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
I haven't done a RHEL7 installation from scratch in quite some
time, but with respect to the software selection stage, it gives
you a handful of possibilities (Minimal Install, Basic Web Server,
Virtualization Host, etc.), and with any of those selections you
would get the standard kernel-<version> package. I don't even
think it's possible to get the kernel-debug-<version> package
unless you did some kind of custom installation, or if it was
installed after-the-fact.
Your system should have log files in /root that show what packages
were originally installed on the system. Check them for evidence
of which kernel was installed.
