One possible solution for an issue when /etc/guix/acl file exists, but points to a non-existent location. This can for example happen if one is reinitializing the system, and remove only /gnu/store and /var/guix, keep the rest okay. This is a major advantage of guix as compared to other distros that usually need you to reinitialize the whole root partition. But this will leave the user with acl file pointing to non-existent location. The file-exists? procedure will return #f for broken symbolic links. I think that another reason one would get this issue is, if one was booted in a live iso, chrooted, fixing their system. They would switch generations to one with different acl file, delete other generations gc rooting the original acl file and then gc. One could do this approach for example when recovering from file corruptions in the store, to get rid of the unsubstitutable paths that can't be repaired with guix gc --verify. This fixes the issue by looking for type of a file through lstat, instead of relying on file-exists?. If the symlink is a broken symlink, it is removed. Other than that the old behavior is kept: - If regular file, back it up - If symlink pointing to the store, remove it - If symlink not pointing to the store, back it up * gnu/services/base.scm (substitute-key-authorization): Check if acl file is a possibly-dangling symbolic link.
