Hi. The last paragraph of [[info:guix#Invoking guix package]] says: However, note that package transformations are lost when upgrading; to preserve transformations across upgrades, you should define your own package variant in a Guile module and add it to ‘GUIX_PACKAGE_PATH’ (*note Defining Packages::).
This contradicts the earlier information, in the same section, about `guix package -u': When upgrading, package transformations that were originally applied when creating the profile are automatically re-applied (*note Package Transformation Options::).
