Red Hat and CentOS systems aren’t booting due to BootHole patches:

Early this morning, an urgent bug showed up at Red Hat's bugzilla bug tracker—a user discovered that the RHSA_2020:3216 grub2 security update and RHSA-2020:3218 kernel security update rendered an RHEL 8.2 system unbootable.

[...] The patches were intended to close a newly discovered vulnerability in the GRUB2 boot manager called BootHole.

[...] Unfortunately, Red Hat's patch to GRUB2 and the kernel, once applied, are leaving patched systems unbootable. The issue is confirmed to affect RHEL 7.8 and RHEL 8.2, and it may affect RHEL 8.1 and 7.9 as well. RHEL-derivative distribution CentOS is also affected.

Red Hat is currently advising users not to apply the GRUB2 security patches (RHSA-2020:3216 or RHSA-2020:3217) until these issues have been resolved.

Ubuntu and Debian are also apparently affected.

    Now Poettering can have an excuse to absorb GRUB into systemd. You see, if this was part of the systemd cluster** you could read out the binary log with another systemd gizmo... but gee whiz kids, there is NO logs. Just didn't boot.
    I wonder who at Red Hat is doing the 2020 equivalent of Balmer levitating chairs at MS. I'm sure Linus T who works there will have some choice words sooner or later.

    I'm surprised red hat is using grub.

    You joke but systemd already absorbed gummiboot.

      I wondered what happened to that, thanks.
