How would this work when there are optional rpms in the module?
You do not need to install every rpm in eg the php module (different graphics/database
backends) for that module to be useful, but every version of the module will have the rpm
as an option which wont work outside a module of multiple rpms.
Glad you ask, I wasn't precise...
Well, I didn't mean everything always needs to be squashed, instead,
it would be an optional step in modulemd processing. For some
use-cases (like delicately compiled postgresql server), you can create
a single rpm that contains all - postgresql-server, postgresql,
postgresql-libs compiled in a specific way, optionally with some
postgresql modules pre-included, so it would be let's say time-series
optimized postgresql. Here it makes sense to make a single rpm from it
- you install that and you are all set up for your use-case.
Then there are language stacks where you might want to build things in
a specific order - there nothing really needs to be squashed (or
certain subset can if it makes sense) but you can still use modularity
to easily batch-build certain rpms. If there are runtime optional
deps, they can be described by Recommends/Suggests.
Basically, once a "module" (things that comes from modulemd) is built,
it should be put into normal repos and the "module" boundary should be
forgotten (unless it is a single rpm), i.e. "module" is a built-time
thing, at install-time we just have standard packages with standard
deps.
dnf interface could be kept given that we "Stream" rpm property is
added. This is still a bit rough what I am saying but hopefully it
makes at least a bit of sense...
