Regression introduced by 44c64fef16ed566786c8db276085b484c9d233f3. The services.xserver.layout option allows to specify more than one layout separated by comma, which the commit above didn't take into account. This is very similar to @lheckemann's pull request (#26984) but differs in the following ways: * Print out the full list available layouts (as suggested by @0xABAB in [1]). * Loop over $layout using the default IFS (and thus no need for escaping ${cfg.layout}), because the layouts won't contain white spaces. * Re-do the error message, which now uses multiple echos instead of a heredoc, so the line is wrapped according to the viewers terminal width. I've tested this with several good and bad layouts and also against the keymap NixOS VM subtests.
