Hi Matt: Is it possible to update the version of grub?
I suggest you search the mail archives of sisuite-users and sisuite-devel, I think Mark Seger have perhaps related issues with grub, but he's using cssis devices though.

I did find that it's -something- with the version of grub in rhel3, 0.93, as I don't get this issue if I build and install 0.95 grub before taking an image. It's just strange that it only happens when installing grub from withing the systemimager/sytstemconfigurator install process, it works fine from within the actual RHEL3 OS. I'm just using gunzip and gzip with no options to uncompress and compress the images. Any other ideas?
