From d5eb05f01ea59da8435e9df4f15835edbb31a30e Mon Sep 17 00:00:00 2001 From: Xinglu Chen Date: Sat, 30 Oct 2021 12:42:27 +0200 Subject: guix home: import: Make the user to specify a destination directory. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Copy the appropriate the relevant configuration files to the destination directory, and call ‘local-file’ on them. Without this, ‘guix home import’ will generate a service declaration like this (service home-bash-service-type (home-bash-configuration (bashrc (list (slurp-file-gexp (local-file "/home/yoctocell/.bashrc")))))) but when running ‘guix home reconfigure’, the ~/.bashrc file would be moved, so when running ‘guix home reconfigure’ for the second time, it would read the ~/.bashrc which is itself a symlink to a file the store. * guix/scripts/home/import.scm (generate-bash-module+configuration): Take ‘destination-directory’ parameter (modules+configurations): Copy the user’s configuration file to ‘%destination-directory’. * guix/scripts/home.scm (process-command): Adjust accordingly; create ‘destination’ if it doesn’t exist.
