When calling update-grub, it scans all devices for operating systems to put into the GRUB config. It even mounts all block devices to do the scan. I'd like to avoid this and let it scan only a number of configured directories, in my case only /boot.
This is due to os-prober invoked by update-grub. To avoid it, you can either - remove the os-prober package - or add GRUB_DISABLE_OS_PROBER=true in /etc/default/grub.
