I guess it is just a matter of personal preference but I find defaultenv-1 easier to understand and easier to manage. With defaultenv-1 we basically have just one configuration file to edit (/env/config) and optionally init_board and/or boot_board (which are not needed in a majority of the cases). So everything you need to know/edit/tweak is in /env/config. With defaultenv-2 the "board configuration" is scattered through a number of tiny files, some of which contain just a single value (see for example nv/autoboot_timeout or nv/user). I find this more difficult to manage -- you need to edit a lot of tiny files instead of just one. Also I feel that the flow of control is less obvious for the same reason. I'd say defaultenv-1 feels more "imperative" and defaultenv-2 feels more "declarative", and I prefer the former. But I am fully aware that this is just a matter of personal preference :) Guillermo _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
