Description Martin Wilck 2016-02-09 14:06:46 UTC

Description of problem:
If tboot is installed and active, and the kernel package is updated with "yum update kernel", the tboot entry in /boot/grub2/grub.cfg or /boot/efi/EFI/redhat/grub.cfg still refer to the old kernel package

Version-Release number of selected component (if applicable):
grubby-8.28-17.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. configure RHEL 7.2 for booting with tboot
2. update the kernel package

Actual results:
The "boot" boot entry is still the same as before, referencing the previous kernel. This will be so even if that kernel has been uninstalled.

Expected results:
tboot entries are added for the new kernel, or changed from the old one to the new one.

Additional info:
This is because the kernel %post script just calls grubby to an entry, and grubby doesn't support tboot.

WORKAROUND: manually run grub2-mkconfig as appropriate for the system (legacy or UEFI) after the kernel update.

Please attach the config file as it appears and how it's supposed to appear.

Changing needinfo, as Martin is no longer at Fujitsu Technology Solutions.
Japanese divisions have taken over the bugzillas.
