hm, on some machines there is a boot device chooser when pressing F12
or something like that when the computer just powers on. maybe you
have something like that and it didn't tell you?

I'm not 100% sure, but afaik this is the config file for those who use
grub2 as their bootloader. quite a lot changed from grub 1 to 2 and
this is part of it I think.

only if you make 'persistence' work, i.e. have a usb-stick or hdd
plugged to your computer during boot which contains a ext2 filesystem
and the disk label 'live-rw'. then, everything should work as expected.

it is, I agree :)
but here it comes:
liveUSB/CD/DVD = root filesystem in a file called "filesystem.squashfs"
this has the advantage that everything is quite
heavyly compressed and so fits more on the CD/DVD/USB
hdd install = root filesystem on hdd and not compressed in a file
