- this partially reverts b3a8287b which prevented BOOTENV as set by config_distro_boot.h being appended to CONFIG_EXTRA_ENV_SETTINGS
- distro_bootcmd can do everything the nested loop can do:
- boot from usb
- arbitrary boot order
- set arbitrary boot partition
- search arbitrary list of prefixes
- load a boot.scr
- in addition to that, distro_bootcmd:
- is the standard boot mechanism for distros (see doc/README.distro)
- thus we can replace hard-to-read custom code
- works with extlinux.conf (needed for debian-installer)
Lots of thanks to @vagrantc for helping me with this! :D
