PXE Booting Ubuntu - Anyone with experience?

[sc8nt4u]

I want to get PXE booting up and running under Ubuntu 11.04 or 10.04 LTS.

How much ram should is enough to run Ubuntu + Bitcoin stuff? Also, I was just wondering how it went overall.

Do you want to boot a Live Disk or from of RAM Disk or do you use NBD or NFS? What do you mean with Bitcoin stuff? Bitcoind needs at least 512 MB. But sometimes I saw the OOM killer going on rampage with that less RAM. 1GB is a safe value for headless bitcoind. I you however use a ramdisk you have to add it to the size of the ramdisk.

I'm about to launch 10 clients (30 video cards) online to do some GPU mining at a colocation facility on a full rack. I would like to simplify the management of the systems by PXE booting from a PXE server hosting the PXE image. I would be using a ramdisk so that I can perform updates on the PXE image and have it applied to all the clients at once. Would this be the optimal solution?

The clients would be running the bare minimum in Ubuntu to get GPU mining up and running with a slight overhead. How much memory do you think I need?

Any results?

Decided to not do it and risk downtime.
