Here's a (reduced) snippet I have from my home-config (and previously in
my manifest file):
(define %my-package-list
(list "git"
"git:send-email"
"git-annex")
(define package-list
(map (compose list specification->package+output)
(filter (lambda (pkg)
(member (or (%current-system)
(%current-target-system))
(package-transitive-supported-systems
(specification->package+output pkg))))
%my-package-list)))
(%current-target-system) doesn't currently work with guix-home but I
figured I'd have it ready. package-transitive-supported-systems makes it
so that git-annex, which shows as supported on aarch64-linux, isn't
added because ghc, one of its dependencies, isn't supported on
aarch64-linux.
