Let's assume for a minute that someone (no names mentioned, 'cause it's me) has remastered tinycore.gz beyond the point that he had originally intended, and now there's no way to boot that particular system into a clean state with which to test extensions.
Is it possible to add a clean tinycore.gz file to the same boot partition, with another name, so it could be used as a testing system? Wouldthat require a new initrd, or just a new grub entry?
