I started off chasing an issue of changing the GRUB2 (root) password for some of my systems, that a vendor provides me patches for.
At first I attempted to use grub2-mkpasswd-pbkdf2; and copy the resulting string into /boot/grub2/user.cfg. That did not work for me as it always has in the past. Fooie! I discovered another place where the GRUB2(root) password hash was being stored.
Then I discovered a problem after copy/pasting the hash into /etc/grub.d/40_custom, and executing the command
Code: Select all
grub2-mkconfig -o /boot/grub2/grub.cfg
Can someone else please confirm whether or not grub2-tools-2.02-0.81 package is doing the same thing on their system and get back to me ASAP? Please?
I confirmed the /etc/default/grub file did actually come from grub2-tools-2.02-0.81, but I cannot remember how to validate the file has been changed since extraction from the RPM that delivered it. Can you help with that too please?
