Correctly? Store items are kept indefinitely. You can use guix gc to remove them. But this of cause works only if they have zero references pointing to them, i.e. there is no other dependency from the store or a profile generation linking to it. I'm not sure if I understood you fully, I hope my answer is the right one to your question. Since a week or so we decided to invite people also to write in their language and not only in English. If that helps you, under "Mailing List" you will find the list of languages that are understood by Guix developers (to be growing): https://www.gnu.org/software/guix/contact/ Björn
