I now presume there are two bugs, most probably related...
1- Failure to reconfigure grub properly OR update the init image when invoked through regular apt process. I cannot tell for sure but, if I only apply a kernel update using dist-upgrade it seems to work ok but when there are a lot of pending updates and some of them requires to either update-initrd or update-grub (can't tell), i get a grub rescue prompt with: "error: ELF header smaller than expected." 2- Failure to apply grub update: Yesterday there where a few updates but nothing noticable such as a kernel upgrade. Although there was a grub update comming in. After rebooting I got this error in a grub rescue prompt: "error: invalid arch-independant ELF magic." The exact same problem had happend the night before and curiously enough it matches the apt cache dir content.
