Hi all,

I can replicate this having just done a yum/dnf update.

The file /etc/default/grub has just been dropped in by a new version of grub2-tools (according you yum whatprovides) with the line:

GRUB_ENABLE_BLSCFG=true

However the grub2.cfg file was not updated so it seems that mkconfig didn't happen automatically.

Using the command below I have reset the flag:

if [ -f /etc/default/grub ] ; then grep GRUB_ENABLE_BLSCFG /etc/default/grub && sed -i.bak -e 's/GRUB_ENABLE_BLSCFG=true/GRUB_ENABLE_BLSCFG=false/' /etc/default/grub; fi

Change log listed at https://rpmfind.net/linux/RPM/centos/8-stream/baseos/x86_64/Packages/grub2-tools-2.02-123.el8.x86_64.html tells me:

* Fri Feb 18 2022 Robbie Harwood <rharwood@redhat.com> - 2.02-115
  - Re-arm GRUB_ENABLE_BLSCFG=false
  - Resolves: #1899903

In theory, yum update grub2-tools followed by a reset should cure this for all time on CentOS 8, I hope.

Thanks

Jamie

Subject [bitfolk] Keep an eye on your CentOS Stream 8 grub.cfg for "blscfg" being introduced

Hi,

In this week's maintenance one customer VM running CentOS Stream 8

failed to boot because its /boot/grub2/grub.cfg file contained bls

commands which BitFolk's (upstream) Grub does not understand.
