02/02: services: configuration: Revert to a working ‘guix home’.


From: guix-commits
Subject: 02/02: services: configuration: Revert to a working ‘guix home’.
Date: Wed, 16 Nov 2022 19:19:38 -0500 (EST)

nckx pushed a commit to branch master
in repository guix.

commit 39e4e00f75be8055300cb0afffb8bd4b4d35f2cc
Author: Tobias Geerinckx-Rice <me@tobias.gr>
AuthorDate: Sun Nov 13 01:00:00 2022 +0100

    services: configuration: Revert to a working ‘guix home’.
    
    This reverts commit 543d971ed2a1d9eb934af1f51930741d7cc4e7ef, and
    its dependent commit 9b21cd2e9a614f1937769caf3917a791b151d841, which
    appear to have triggered a recent wave of ‘guix home’ regressions
    involving (services (list (service home-bash-service-type))):
    
    In gnu/home/services/shells.scm:
        504:7  3 (home-bash-extensions #<<home-bash-configuration> package: 
#<package bash@5.1.8 gnu/packages/ba…> …)
    In unknown file:
               2 (append #<<location> file: "…" line: 14 column: 12> ())
    In ice-9/boot-9.scm:
      1685:16  1 (raise-exception _ #:continuable? _)
      1685:16  0 (raise-exception _ #:continuable? _)
    
    ice-9/boot-9.scm:1685:16: In procedure raise-exception:
    In procedure append: Wrong type argument in position 1 (expecting empty 
list): #<<location> file: "…" line: 14 column: 12>
    
    I should love to dive in & fix this rather than revert, but urgently
    need sleep.
