Description of problem:
Maybe this is intentional:
the mentest86+ package contains a script (similar to the kernel package) to add
memtest to the bootloaded selection screen. However, this script is just called
on uninstall (and not even conditionally) to remove the entry, so installing
memtest does not add it to the boot menu.
Furthermore, I suspect that updating the package will remove an existing entry,
but this is speculative.

Version-Release number of selected component (if applicable):
memtest86+-1.65-4.1

How reproducible:
Always

Steps to Reproduce:
1. Install memtest86, boot
2.
3.
  
Actual results:
No entry in boot menu

Expected results:
Entry in boot menu
