The configuration files will be created by a simple python application
(which the update-crypto-policies will transform into). You will
specify just the modifications that should be done to the base policy.

Please see 
https://gitlab.com/redhat-crypto/fedora-crypto-policies/tree/custom-policies 
to get the idea.

We might continue shipping the "unmodified" configurations in
/usr/share but I do not see much benefit in that except for being able
for the sysadmin to look at how the unmodified individual
configurations look like without applying the policy to the system.
