Why is grub still probing when I disabled that feature? [solved]

[bpeary]

During an upgrade to kernel 5-15.0-48, the output said grub was probing for other OS's. I thought probing had been turned off upstream because of security issues with the process. Further, I have disabled probing in /etc/default/grub:

Code: Select all

GRUB_DISABLE_OS_PROBER="true"

With four OS's on this machine, probing is a very slow process, particularly annoying because I don't even use grub within Mint. (Cinnamon won't let me uninstall it.)

Version of Mint?

Adding that line on /etc/default/grub does not work on LM 21 edition (see this post).

You will need to edit /etc/default/grub.d/50_linuxmint.cfg

Code: Select all

xed admin:///etc/default/grub.d/50_linuxmint.cfg

and change last line

GRUB_DISABLE_OS_PROBER=false

to

GRUB_DISABLE_OS_PROBER=true

Save changes, close editor and run

Code: Select all

sudo update-grub

Thank you!
