Description Renaud Métrich 2022-07-15 14:15:52 UTC

Description of problem:

When having TBoot configured on the system, executing `grubby --info=ALL` doesn't print TBoot entries.
This is due to `grubby` printing BLS entries only (through executing `/usr/libexec/grubby/grubby-bls` internally).
Because TBoot and BLS are incompatible for now, `grubby` needs to be enhance to print "legacy" entries found in `/boot/grub2/grub.cfg` as well.


Version-Release number of selected component (if applicable):

grubby-8.40-55.el9.x86_64

How reproducible:

Always

Steps to Reproduce:
1. Install TBoot and regenerate the Grub menu

  # yum -y install tboot
  # grub2-mkconfig -o /etc/grub2.cfg

2. Execute `grubby --info=ALL`

Actual results:

BLS entries listed only, no TBoot entries (present in `/boot/grub2/grub.cfg`)

Expected results:

All entries displayed while booting

Renaud,

This feature request cant be granted now due to following reasons:
a. Intel is looking into deprecating tboot.
b. the attached customer case is closed
