Perlish code follows...
$current = `eeprom nvramrc`;
$future = $current . "\ndevalias bootdisk /path/to/whatever";
`eeprom nvramrc $future`;

I think you could parse through /etc/path_to_inst for ce devices of
instance 0, but I'd prefer the first way. It's more general in case
there were anything else already in nvramrc.
