[Bug 1613260] [NEW] update-grub (grub-mkconfig) includes all kernels in boot, regardless whether version is in /lib/modules

[Peter Passchier]

Public bug reported:

All kernels/initrds in /boot are included, also if they would never
work. Below is a patch that fixes this.

1. Ubuntu 16.04.1 LTS (but it has always been like this)
2. grub-common 2.02~beta2-36ubuntu3.2
3. Only the kernels/initrds that have a version that is installed are listed on grub-mkconfig
4. All kernels/initrds in /boot are enumerated
