tc2.2rc1 isohybrid - remind me what problem this solves?

[bigpcman]

Upgraded iso now using isolinux 3.8.2 to easily support isohybrid (see the new syslinux extension)

I read through the syslinux info and still am not sure what new functionality the "isohybrid" offers? Could someone elaborate further as to what problem this solves. I didn't see any threads that explored this idea.

By running the utility isohybrid on the supplied tinycore iso or microcore iso results in a new iso without any other steps involved. On some machines copying this new iso to pendrive provides an additional bootable option to the usinstall script currently offered.
