Thanks Simon, I've pushed the first 3 patches from this series to the
master branch now.

For the changes regarding propagated-inputs though, I'm not sure this it
the right direction. Firstly, I think it's possible (and maybe
desirable) to keep the 'fix-paths phase, even if the inputs are changed
to be propagated.

I know you say this is related to yosys show in the commit message, can
you elaborate on why these packages are necessary to have in the users
environment?

Thanks,

Chris
