Right, in EL-5 version there's older livecd initrd generator script
called "mayflower" which is limited to in-memory overlay (sparse file
in initramfs).
It does not support disk based overlay, that was added later in Fedora
mkliveinitrd after RHEL5 branched.
Ahhh, and this would be a limitation based on physical memory in the
machine where the iso is being created? So it would be suicidal to try
creating a 4GB root fs on a machine with only 2GB physical ram?
Perhaps I'll try using a newer version...
Thanks!
