This eases using them. I tried that. It seems that there is a precident to use /variant for the variable. However / is not permitted in the name > +(define-public util-linux > + (package > + (inherit util-linux/base) > + (name "util-linux") > + (source (origin (inherit (package-source util-linux/base)))) I'm curious: Why do you need to inherit the package-source here? Well I don't actually *need* to. I could have copied it. But I thought that having 3 copies would make maintenance difficult---somebody might update one, but forget the other two. -- Avoid eavesdropping. Send strong encrypted email.
