Yes. The posix extension embedded in rpm is and will remain a fork: rpm 
needs to limit what functionality is available through the posix 
extensions in order to protect itself, and also to protect package 
scriptlets against changes like this.

The tougher question is going to be what to do if/when Lua introduces 
dramatically incompatible changes in the language itself.
