 We can list /boot/vmlinuz-* or /boot/initrd-*; it does open the
 question of support for non-Debian kernels (e.g. self built ones),
 backups, or generally files hanging around there.  It also means we
 don't get the information the official way (according to kernel
 packaging policy).  grub does look at /boot/vmlinuz-* /boot/vmlinux-*
 /vmlinuz-* /vmlinux-* though, so why wouldn't we?  :-)

 It might or might not relate to installed kernels at all though, so
 that update-initramfs triggers flash-kernel and we flash and reflash
 the same local kernel again and again.

 depending on how many files we end up putting there.

 Not sure why we'd need to do anything special there?
