What I meant is that the version string alone is insufficient. You can have multiple variants of a package with the same nominal version, but the differences are in the closure of the package. When Guix is upgraded in between two invocations of “guix package -u” seeing the same “version” of a package to be upgraded to is a common occurrence. > How can the inputs have changed if Pierre is just running "guix package > -u" repeatedly? That bit of information was not available to me when I composed my initial response. If Guix is not changed in between then this behaviour seems to be a bug. -- Ricardo
