I've been fighting my manifest to try to get "git" and "git:send-email" both included, while using package transformations. For the sake of brevity, here's a stripped down version of my manifest:
(packages->manifest
(map specification->package+output
'("git" "git:send-email")))
Here's what I learned from some experimentation:
(cmd)scheme@(guile-user)> (specification->package+output "git:send-email")
$14 = #<package git@2.32.0 gnu/packages/version-control.scm:176 7f730e918320>
$15 = "send-email"
(ins)scheme@(guile-user)> (list (specification->package+output
"git:send-email"))
$16 = (#<package git@2.32.0 gnu/packages/version-control.scm:176 7f730e918320>)
(ins)scheme@(guile-user)> (list (specification->package+output "git"))
$17 = (#<package git@2.32.0 gnu/packages/version-control.scm:176 7f730e918320>)
Meanwhile, (specifications->manifest '("git" "git:send-email")) does
actually return a manifest with both the "out" and the "send-email"
outputs of git.
(package->manifest-entry (specification->package+output "git:send-email"))
returns a manifest entry for "git:out" and
(package->manifest-entry git "send-email") returns a manifest entry for
"git:send-email".
