Maybe I'm missing something here. update-grup creates a grub.cfg with menuentrys for every kernel it can find - except a menu entry using /vmlinuz on the current root as the kernel! But in debian, the obvious default is whatever kernel /vmlinuz points to. I made a custom entry to do just that - but why isn't it in the debian version, and why isn't it the default? Am I missing a config setting here? --
