What constitutes an EC2-specific customization? Eucalyptus functions very similarly to EC2, so it will likely need the same tweaks as well.
Right now, the differences are mostly to do with grub2. (Not only would grub2 be superfluous, it doesn't work at all in the current build system.) Syslinux is smaller, and the new build process shouldn't throw up that kind of barrier, so for F19 hopefulyl we can just leave those the same.
The other difference is that we do
echo "hwcap 1 nosegneg" > /etc/ld.so.conf.d/libc6-xen.conf
in the EC2 image, to work around an issue with the version of Xen shipped in RHEL 5.0 (and fixed in RHEL 5.2). I hope that's not a problem for most Eucalyptus deployments.
It's possible we might have other divergence in the future, if we need other work-arounds like that, or if people _really_ like "ec2-user' for EC2 and "fedora-user" or something elsewhere.
