The GUI libraries will be required by the dynamic linker in order to run 
the binary if the GUI was enabled at compile time.  IOW, there are two 
completely different binaries.  I would be nice if it worked the way you 
describe, but I think it would be many man-years of work to implement all 
the changes in emacs required.

Well, then I guess my preference would be to eliminate the -nox subpackage 
from Fedora.  We can continue to support it for RHEL, since there will be 
headless servers, etc, that don't need all the GUI infrastructure.

FWIW, on Debian, there are

/etc/alternatives/vi
/etc/alternatives/emacs

etc, etc.  So Debian uses the alternatives mechanism heavily in this 
respect.  I'm not suggesting that Fedora should emulate this, just making 
the observation.
