I understand that this can be done by turning off DYNAMIC_GHC_PROGRAMS and associated build options. Is this possibility going to be kept going forward, or will it be deprecated once dynamic GHC is fully supported on all platforms?
PS This is for Linux x64.
We may yet go back and turn DYNAMIC_GHC_PROGRAMS off by default, it has yet to be decided. The worst situation would be to have to support both, so I imagine once we've decided one way or the other we'll deprecated the other method.
Is it just shortage of space, or is there anything else that pushes you towards DYNAMIC_GHC_PROGRAMS=NO? Isn't disk space cheap?

Speaking for myself, but I've noticed compilation times can be much shorter with DYNAMIC_GHC_PROGRAMS=NO. On one project using dynamic ghc added about 18 minutes to the build time (45 minutes vs 27). That's significant enough that we're leaning towards static ghc for now.
