That won't work nearly as well as you'll be making assumptions about the
commands as you go.
ie: yum-queue install foo*
yum-queue erase foo*
not really the same command and you can't treat foo* as one package.

I disagree and I also tend to follow the rule that if you find yourself
writing more than 20 lines of bash, you need to change languages - an
exception to this rule is init scripts.
The other problem with the save format is:
1. the separators are going to be a problem
2. the storage mechanism will cause problems too
Specifically you use space separators and "" segments
When things start getting very complex, as there are no character
limitations on what can be in a package name, it's going to get hairy.
Finally, I'd prefer if things for yum all stay in the same language,
having a hodge podge of languages is hard to deal with and it's just not
sensible in the long run.
