This is not possible with guix system easily. Guix channel commonly keeps only one version of a package in current source code, so you cannot just specify older version to stay on, when you guix pull, and reconfigure, everything will be at the versions that are declared in the channels. If you aren't ready to update, use guix instance with same channels as with previous reconfigure. There are some exceptions, like gcc, where even older major versions are kept, and there you can refer to older versions, either through symbols or through specifications. If you wanted to pin some packages, you can use inferiors, but they aren't easy for achieving the goal you want of keeping packages at given version until you want to update. > > Or maybe their is an option flag I missed on the command `guix system > reconfigure' ?
