Need to see more info for Grub entries at boot, maybe partition labels

[Moderator BobC]

On each partition there is a label, and I always enter a label to remind me about that partition, as I have many partitions that I create and load to test different scenarios with as clean of a setup as possible to be able to reproduce problems and get good tests of solutions. Of course, there might be another, better place to put this info, but currently I put it in the partition label so I can remember what is in each.

When I boot, if I could see that info it would help a lot.

There look to be different types of entries generated in /boot/grub/grub.cfg by the different update-grub related scripts it looks, and the main entry from 10_linux doesn’t tell you what partition it’s on or any info about it except the version:

### BEGIN /etc/grub.d/10_linux ###
menuentry 'antiX-19.1 Marielle Franco' --class antix_19_1 --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-9dd9ef75-417a-4169-8221-34342d349716' {

submenu 'Advanced options for antiX-19.1 Marielle Franco' $menuentry_id_option 'gnulinux-advanced-9dd9ef75-417a-4169-8221-34342d349716' {
	menuentry 'antiX-19.1 Marielle Franco, with Linux 4.9.212-antix.1-amd64-smp' --class antix_19_1 --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.9.212-antix.1-amd64-smp-advanced-9dd9ef75-417a-4169-8221-34342d349716' {

Looking at the 30_os-prober entries, they do say what partition they are on, but when I get 4 or 5 different antiX 19.1 partitions on the same system, it would be super helpful to be able to distinguish them from one another:

}

Any ideas on how to better identify the partitions when I boot without breaking Grub or OS-Prober?
