Split/install non-free software

[andrewhq]

Add an option to split free/non-free software to allow installer to dynamically install the non-free bits like codecs.

[ikeydoherty]

To elaborate:

• By default the Solus ISO contains distributable, non-free software.
• Freedom is two-fold: The freedom of the code and project, as well as the freedom to decide whether to use free or non-free.
• The installer will therefore have a tickbox to install the non-free bits (additional firmware, "bad" "ugly" codecs, etc.)
• The relevant packages in Solus will be modified to continue to support existing installations through upgrade with no breakage, but modified to remove any hard dependencies, enabling a more Libre ISO.

To investigate (notes to self):

• Is it "enough" to have these in a separate part of the ISO, or does this still constitute distribution?
• If they have to be provided by the repos, then this is impossible. The firmware contains necessary bits for networking and GPUs.
• Should the ISO itself be configured to live boot with these enabled or disabled? Again the distribution question.
• We're rolling release - installing anything over the internet would also have to include an upgrade, making the target installation non-quantifiable. It becomes a complete unknown if it will "work".
• If firmware enables networking - net install is a non starter entirely.
• If netinstall is a potential route: We must then snapshot the relevant additional bits into a release dependent repository and install from there, as upgrading should not be permitted during this step.
• Alternatively, do a full upgrade and install extra bits.
• Most importantly: Go seek information from those who know these things

Which ones?

[ikeydoherty]

The ones that aren't libre, obviously
