This still fails for me, and apparently also on the build farm:

https://ci.guix.gnu.org/build/3266550/details

if I am reading it properly that build is after the described 
patch. The log has the same error as I have locally when building 
openssh

Interestingly, since the openssh release I have this in my 
manifest which *succeeds* in building openssh:


(define-public openssh-next
 (let ((xcommit "1036d77b34a5fa15e56f516b81b9928006848cbd"))
   (package
    (inherit openssh)
    (name "openssh-next")
    (version "9.6p1-1")
    (native-inputs
     (list autoconf
           automake
           pkg-config))
    (source
     (origin
      (method git-fetch)
      (uri (git-reference
            (url 
            "https://github.com/openssh/openssh-portable.git")
            (commit xcommit)))
      (file-name (git-file-name name version))
      (patches (search-patches 
      "openssh-trust-guix-store-directory.patch"))
      (sha256
       (base32 
       "1sary1ig972l4zjvpzncf9whfp5ab8snff2fw9sy5a8pda5n2a7w")))))))

This just refers to the commit that holds the patch, so in theory 
it should be the same as the applied patch, no?

Am I overlooking something?
