Oh, it makes a lot of sense. I mean, most config files are only
touched during installation and during package upgrades. Otherwise
they are practically read-only. During package upgrades or if the
admin really wants to change something he can temporarily remount / to
rw without a problem. This is eprfectly well supported by Debian.
Now, the only stumbling block for this is that some files (like
/etc/resolv.conf) are rewritten from time to time. But that's a bad
bad misdesign anyway and we should really get rid of
/etc/resolv.conf. In the meantime one can do what Debian did and make
resolv.conf a symlink to a writable location.

You are going to have fun with that. Succeeding with moving stuff like
/etc/services to /usr/share is even more unlikely than pushing the
removal of /usr through in Fedora.
