Overriding default config with nvram?

by Blue Swirl

Hi, I'm adding support for nvram variables to Qemu (see attached patches), like: qemu-system-sparc -prom-env "boot-device=zorg" But this only works if the variable does not have any default value in nvram.fs. I'd like to change this so that the nvram values override defaults, but how? For example: qemu-system-sparc -boot n -prom-env "boot-device=foobar" -prom-env "boot-device-foobar=foobar" -nographic -monitor stdio -hda /dev/null Nvram id QEMU_BIOS, version 1, machine id 0x80 CPUs: 1 Welcome to OpenBIOS v1.0RC1 built on Apr 29 2007 07:39 Type 'help' for detailed information [sparc] Booting file 'net' without parameters. 0 > printenv name "options" boot-from "disk" boot-device "disk" boot-device-foobar "foobar" boot-args "" [cut] Here boot-device is overridden to "disk" somewhere later but boot-device-foobar survives.
