Grub2 chainloading to syslinux and isolinux for a multi-boot flash drive
I've been out of the loop for a few years and I need a sanity check on what I'm trying to do here.
Can I configure grub on a flash drive to chainload multiple live cds on a single partition with either syslinux or isolinux such that I would see their native boot menus? Distros like system rescue cd have huge boot menus with a plethora of options that I would like to preserve without reinventing the wheel. Is this doable? What would the grub config file look like?
I learned loop mounting the iso's directly doesn't work with chainloading for some reason, is that true? Extracting the files isn't a big deal so this obviously isn't a game breaker but I was wondering if this was still the case. The posts I saw referencing this were like 5 years old and didn't explain why.
