Description
From src/libexpr/primops.cc,
multiple outputs are not supported in fixed-output derivations
I was looking into making `cacert' a fixed output derivation - but ran into this error. Is there any plan to get these two things to work together? I think you would just need to have a way to specify different hashes for each of the expected outputs.

Research direction
Start in src/libexpr/primops.cc, where the “multiple outputs are not supported in fixed-output derivations” error is reported. Trace how fixed-output derivations and output hashes are represented, then determine the required behavior for specifying different hashes for each expected output; done means multiple outputs can work with fixed-output derivations.
