I like the idea of rawhide-only debug checks like this, but can we add some kind of message to login like this: <idea> This is a pre-release version of Fedora, and is running with extra diagnostics that help find bugs, but impact performance. Please read (LINK TO A WIKI PAGE) before attempting to run benchmarks on this system. </idea> Is there a good place to add this? e.g. /etc/issue ? I'm not sure of how to handle a conditional there.
