I agree modifying sudoers could work too, but you also have the sudo gainroot hack in initfs_flash which is why I decided on this solution
think ext2.img file systems on fat fs MMC including optional features. Think LINUXRC="/dropbear/dropbear.linuxrc" that starts it up by mounting /dropbear/dropbear.img on the fat system and starting the dropbear file inside it..
My intent has been all along as it to be patches for your bootmenu - I have no interest in maintaining bootmenu software - so I'm all ears on how to change things to improve upon your bootmenu and maybe include in the more "official" distribution
