Currently, (guix profiles) has code to build 'info-dir' for packages in profile. As mentioned in TODO, IIUC, we should move the code to 'texinfo'.
Other usecases include: * hicolor-icon-theme: use gtk-update-icon-cache to get 'icon-theme.cache'. * shared-mime-info: use update-mime-database to get 'mime.cache'. * desktop-file-utils: use update-desktop-database to get 'mimeinfo.cache'. ? glib: use glib-compile-schemas to get 'gschema.compiled'. For schemas, it's always safe for packages in system profile, but may broken for user profile: user had install package A user update the guix disto, A -> A' has incompatible schema change user now install package B' which depend on schema of A' B' will crash if we have schemas from A and B'. If we make A a propagated-inputs of B, dose A will be update to A' when install B'? If so, that's great, we can even get rid of glib-or-gtk-build-system.
