[olug] yum install dracut-config-generic should help with changing the underlying architecture

[Rob Townley]

Are you moving an running OS image to a different storage array or from one
hypervisor to another or otherwise changing out the underlying “hardware”?

Spent way too much time moving from jbod to raid mirror in part because
CentOS 7 would not boot because it did not have all the kernel modules for
the raid mirror.

Had i simply yum installed dracut-config-generic beforehand, it would have
likely booted the first time.

Hopefully, this saves someone an hour or two.
