I'm having trouble learning how to add multiple boot configurations to Debian's Grub2.
Debian has Grub pages at https://wiki.debian.org/Grub and https://wiki.debian.org/GrubConfiguration, but they lack practical examples for multiple boot configurations. Would someone please update update the pages and discuss multiple boot configurations like detailed below? Thanks in advance. ***** Here's the back story... A Debian maintainer broke us under X32 (https://wiki.debian.org/X32Port). We needed to enable X32 under Debian 8 and perform specific testing in that configuration. But we also want to retain the original Debian 8 for testing, too. So what I want in my Grub menu during boot is: * Debian GNU/Linux * Debian GNU/Linux (X32) * Advanced Options ... * Memory Test ... Debian GNU/Linux should boot with default options. Debian GNU/Linux (X32) is new, and it should boot with GRUB_CMDLINE_LINUX="syscall.x32=y" in accordance with https://wiki.debian.org/X32Port. The configuration changes should also survive various updates and dist-updates. Trying to get Grub into a "multiple boot options" based on the docs is proving to be difficult. ***** And to be clear, I don't care about examples like below. I don't boot like that; rather I select a Grub menu item. grub> kernel (hd0,0)/vm
