[Fedora-livecd-list] size of device on which anaconda lays down a filesystem?

Hi, while working on creating some images, I've encountered something strange and was wondering if anyone could help? This relates to iso's created with livecd-tools-013-8.el5.1 from epel. I've been playing with making .ks's for machines of different characteristics (like different amounts of memory installed). I'd assumed I'd need to make images with defined fs's of <= installed system memory. I was surprised to find I did not? I was able to boot an image w/ an 8GB / on a machine with 4GB memory. I encountered problems if I used more than 1GB of fs space on /. So I created an image with a 3GB /, and tried the same test on the same machine with 4GB memory, but encountered the same problem if I tried to use >1GB of /. It's like the block device that lives under the filesystem isn't actually "as big" as the fs that's layed down on top of it? I get I/O errors, and kjournald complaining about not being able to talk to the device; and then the kernel drops / to read-only. Any ideas? Thanks!
