Hello, When using grub2-set-default, it is an easy matter to set the default OS by number, but how do I select a nested OS? These are the OSs listed under the various "advanced options" listings.
I saw this information on a webpage last week, but of course I can't find it now. IIRC, it was something like "grub2-set-default x,y" (but of course that's not it).
Anyone know what the correct syntax is for the nested systems, using the number starting from "0"?
