- Previously, the grub.conf file was not properly updated after a kernel update with the tboot bootloader. This was due to a bug in the grubby tool which caused it to improperly interpret the grub.conf stanzas that had tboot in them. This update enables grubby to read the HYPERVISOR and HYPERVISOR_ARGS parameters from the /etc/sysconfig/kernel file in order for tboot to perform as intended.
- Prior to this update, yum and anaconda upgrades could have failed with a kernel panic on the AMD64 and Intel 64 architectures due to the RAM disk image not being found. This only happened when tboot was installed, and the kernel "%post" or "%posttrans" scripts were run. This update adds the initramfs disk image to the grub entry, and kernel panic failures no longer occur in the described scenario.
