This is what is generated by default when I boot the host at 1st time : set root='hd0,msdos1' root=/dev/vda1 and this is what I would like to the end : set root=(hd0) root=/dev/vda
This makes sense only if the drive has no partition table and is filled entirely with a single filesystem, like a floppy disk. But this drive seems to have a partition table.
my guess, I should play with the "boot/grub/custom.cfg" file? Do you have some examples?
The contents of custom/cfg will be sourced at the end of grub.cfg at run-time. But I fail to see how it will change previous boot menu entries.
Also, I realized that enabling GRUB_DISABLE_LINUX_UUID by true, that still generate UUID on the file. Is is that expected?
Yes. This option only affects the root= parameter in the Linux kernel command line, not the way GRUB itself looks for devices for its own use.
