I installed CentOS 7 and can't reproduce this. It's only using 188MB
with five kernels, three of which are debug.

Is this possibly related to kdump? Is it possible for stale kdump
files to accumulate and that's what we aren't seeing in the RHEL bug
report? How big can those get? Maybe they shouldn't be going on /boot?
In a single update, the used space jumps 181M, but that doesn't seem
related to kernel (debug or not) installations. Debug kernels don't
use that much more space.
