Good suggestions. > Also, I think there should be a search facility, with incremental search > fashion.

Right. And that's exactly what this command do, I think. >> `R' >> Roll back to the previous generation of the profile >> (`guix-roll-back'). This undo the last transaction.

How do you > feel about it? Cool. Fine with me as an bonus work item. Thanks for your attention and suggestions. I'll continue learning the tools. -- http://www.gnu.org/software/emacs/
