Hi, Stephen.

FESCo has requested that I submit the module policy once more to the

* Packages *MAY* convert from a non-modular package to a modular
default stream (or the reverse) only in Rawhide or during Fedora
upgrades.
* Default streams *MUST NOT* provide a binary RPM with the same
package name as a non-modular RPM in the same release except in the
case of a transition from one to the other.footnote:[Modular packages
shadow non-modular ones. This rule ensures that we don't have any
shadowed packages in the default package set.]
[1] Transitions to/from modular are already forbidden in Fedora
releases, so saying "in the same release" makes no sense. I'd say "in
rawhide or during Fedora upgrades".
* Default streams *MUST NOT* provide a binary RPM with the same
package name as an RPM in a default stream in the same release except
in the case of a transition from one to the other.footnote:[In this
situation, whichever has the highest NEVRA would win the depsolving
and could break the other module.]
I guess "transition to another default module" is what is meant above.
* Multiple default streams *MUST NOT* provide the same binary
package
names at runtime.footnote:[They *MAY* provide other well-known names
in the same manner as permitted for non-modular content. For example,
two different default streams *MAY* provide content to be used with
the `alternatives` system or virtual `Provides` for capabilities.]
* Default streams *MUST NOT* provide a package that overrides a
package of the same name in the non-modular content except in approved
cases of migration between modular and non-modular delivery.
This is redundant, already mentioned above[1].

There should be a science of discontent. People need hard times and
oppression to develop psychic muscles.
