Check CPU for AES support during custom-CentOS installation I have custom distribution of CentOS Linux 6.3. The installed system needs CPU support for AES-NI for all services to work properly. **Can I add a check for AES support during the installation?** I'm using Anaconda, but am willing to consider other ways to do it as well.

Thanks Michael Hampton for this answer:

This would require a kickstart script to be used. Fortunately the kickstart script need only be trivial. You may use this alone (for an otherwise normal interactive installation) or as part of an existing kickstart script.


%pre --erroronfail
#!/bin/sh
grep -q aes /proc/cpuinfo || exit 1
%end


If the CPU doesn't show this feature, the script will error exit and the installation will stop.
