No. There are “profile hooks” in (guix profiles) that are used to a similar effect, for instance to assemble the ‘dir’ file that contains pointers to Info documentation. > A program in a package I created is trying to access /var, but has no > permissions.

First, you probably need to pass --localstatedir=/var to this package’s configure state, since at run time it won’t be able to write to /gnu/store/…/var anyway. Second, it will try and fail to create /var. The way to address that is by simply commenting out or patching out the offending commands. See for instance ‘avahi-localstatedir.patch’ or ‘mcron-install.patch’. HTH! Ludo’.
