Hi,

This seems to be the case.  Here are the derivations for the info-dir
hook for the first and then the third profile:

Note that they differ in the inclusion of /gnu/store/h0905d946s3xarcfakan8jnblcdqxs3a-hello-2.10.drv as
a derivation input.

I guess that the problem might be in “profile-derivation”, which defines
“inputs” like this:

    (define inputs
      (append (filter-map (lambda (drv)
                            (and (derivation? drv)
                                 (gexp-input drv)))
                          extras)
              (manifest-inputs manifest)))

I pk’d at the value returned by manifest-inputs and found this:

--8<---------------cut here---------------start------------->8---
$ guix package -p .guix-profile -i hello
The following package will be installed:
   hello	2.10	/gnu/store/md2plii4g5sk66wg9cgwc964l3xwhrm9-hello-2.10


;;; ((#<gexp-input #<package hello <at> 2.10 gnu/packages/base.scm:68 31e4d80>:out>))
1 package in profile
The following environment variable definitions may be needed:
   export PATH=".guix-profile/bin${PATH:+:}$PATH"

$ guix package -p .guix-profile -i coreutils
The following package will be installed:
   coreutils	8.30	/gnu/store/xzgfh8kdxilyymi1a8i97b1nci1iybhi-coreutils-8.30


;;; ((#<gexp-input #<package coreutils <at> 8.30 gnu/packages/base.scm:338 39a7000>:out> #<gexp-input "/gnu/store/md2plii4g5sk66wg9cgwc964l3xwhrm9-hello-2.10":out>))
2 packages in profile
The following environment variable definitions may be needed:
   export PATH=".guix-profile/bin${PATH:+:}$PATH"


$ guix package -p .guix-profile -r coreutils
The following package will be removed:
   coreutils	8.30	/gnu/store/xzgfh8kdxilyymi1a8i97b1nci1iybhi-coreutils-8.30


;;; ((#<gexp-input "/gnu/store/md2plii4g5sk66wg9cgwc964l3xwhrm9-hello-2.10":out>))
1 package in profile
The following environment variable definitions may be needed:
   export PATH=".guix-profile/bin${PATH:+:}$PATH"
--8<---------------cut here---------------end--------------->8---

Should manifest-inputs distinguish between a package entry and a file
entry and paper over the differences?
