... and something else just for grins :-) as i didn't think of it
until right after i sent my msg ...

read -rd $'\0' opts <<EOF
grub=A nice long explantaion about grub :-)
syslinux=And that's why we are teh awesome!
insert_here=I'm just along for the ride

echo "$opts"

that will store the entire heredoc into $opts (remember to use quotes
for output of course); since null is used as a delimiter, and bash
variables/strings are not capable of storing null, this guarantees the
entire doc will be in `$opts`.

it really is ridiculous what bash is capable of ... anyways, carry on,
nothing to see here.
