The user would have to recompile glibc from source. The user will need
to do that from a different system though, as all the user is getting
after upgrading glibc is "FATAL: Kernel too old" on every command
executed. No way to revert to an older glibc, because not a single
command will execute. This is why I don't like bumping this beyond
