On the other hand, the runtime code requires just a s/Ubuntu/Fedora/g, but it isn't useful without the database, and the scripts to write that database have to be essentially rewritten to work with RPM. Another problem is that this assumes the available set of packages is static (the database is generated once at build time and then never touched, that's why it is so fast), so in the context of Fedora, it would require regular rebuilds to deal with the new packages which show up regularly in Extras. An alternative approach would be to query the repository metadata directly at runtime using something like repoquery, but that would be a lot slower. It could however be implemented with only a few lines of bash around repoquery (the single line "repoquery --whatprovides /usr/bin/$1 /bin/$1" would be enough for a basic implementation of command-not-found).
