Hello Andreas, I have now 2 files in gnu/guix/packages/*.scm, for mutt and postgresql: and now I get each time on running guix, following:
guix package: warning: failed to load '(databases)': ERROR: no code for module (databases) guix package: warning: failed to load '(mutt)': ERROR: no code for module (mutt) because 2 files are: databases.scm and mutt.scm I have already installed mutt, with changes, and it works. On the end of file there is word "mutt". Similar for PostgreSQL, only it did not yet compile. Now I get a feeling, if I have 20 files to change or adapt to my system, I will get 20 warnings by each run of guix package manager. Somehow it does not feel right. It would be more logical to have GUIX_PACKAGE_PATH plus one separate file where some modified or user related packages are listed, instead of having the package name on the end of *.scm file.
