I agree, using GUIX_PACKAGE_PATH is such a nice way to keep your own packages. I don't understand why Andreas recommended to use "guix package -f". I think it is suitable to build some development "guix.scm" file (not related, but see =C2=B9). But for user packages, I think keeping them in GUIX_PACKAGE_PATH directories is a much better solution. I also don't recommend to use the same /gnu/packages/*.scm structure, as there may be problems with this. For example, you copied /gnu/packages/databases.scm to your GUIX_PACKAGE_PATH dir and modified some package in it. Then you have to follow the changes in this file made in Guix, and update your local databases.scm accordingly all the time. So if you want to keep all your packages in a single file, you can make "/my-guix-packages.scm", add to GUIX_PACKAGE_PATH, and that's it! This "my-guix-packages.scm" file will look like this: --=-=-= Content-Type: text/x-scheme Content-Disposition: inline; filename=my-guix-packages.scm (define-module (my-guix-packages) #:use-module (guix packages) #:use-module (guix download) #:use-module (guix utils) #:use-module (gnu packages mail)) (define-public my-mutt (package (inherit mutt) (name "my-mutt") (arguments (substitute-keyword-arguments (package-arguments mutt) ((#:configure-flags cf) `(cons "--enable-hcache" ,cf)))) (synopsis (string-append (package-synopsis mutt) " (configured with --enable-hcache)")))) --=-=-= Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable And all guix commands will find packages in this file, for example you can do: "guix package -i my-mutt".
