Am I missing something?
Boost has no run-time dependency on tcsh, as shown by: guix size boost | grep tcsh This is probably the reason why tcsh is in ‘native-inputs’, and also the reason why Boost is not grafted in this case. It’s a case where using a graft allows us to not rebuild anything when we know it wouldn’t make any difference. Anyway, the patch LGTM, thank you! Ludo’.
