Are you trying to PXE boot a RAM based OS image? If so, I've actually been working on something similar. I have a different end goal but I think the fundamental concept is the same. After much monkeying around (including basically rolling my own mini Linux distro), I've finally learned enough to get back on track using CentOS as the base. Basically, you just need to use yum with the --installroot option, make a customized /init, move a couple files into place and cpio the whole thing up.

This is basically what I do for an extremely minimal OS image:

yum -y groupinstall base --installroot /tmp/live-image-build yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm --installroot /tmp/live-image-build yum -y install $other_packages --installroot /tmp/live-image-build

A basic /init file: """ hostname somehostname.domain.tld . /etc/profile mkdir dev/pts mkdir dev/shm chmod 1777 dev/shm mount -av ln -sf /proc/mounts /etc/mtab exec ${init} 3 """

cd /tmp/image-build && find . -print0 | sudo cpio --null -ov --format=newc | gzip -9 > ../initramfs.cpio.gz

That's a really simple explanation but it should get you on the right path, assuming you're trying to do what I think you're trying to do. If you're going to need people to be able to store data somewhere, you'll need to come up with some time of remote file system (NFS, Fuse, etc) and sort that out. I don't have much need to store anything, so I haven't played with that at all.

Hopefully this helps.
