| I'm going to post a really basic shell script here to replicate the setup I have on headwaiter (the install on which this article is based).
| | Having had more than one install server disappear, [[koanhead]] is working on automating the setup process. Results posted to github. |
| I will also place the file in the [[Special:ListFiles]] section so it will be wget-able. Later there will be a more refined, general-purpose script on our github.

Computer with bad mobo[edit]
I came across a computer that had a bad motherboard... (memory errors occurred with any ram that i tried)
I'm wondering if that was it.
I'll be there on Saturday towards the end of the session AaronPeterson (talk) 14:56, 31 October 2014 (PDT)
I'm not sure what you mean by 'if that was it'... the server that refuses to PXE boot has OK ram as far as I can tell, the netboot issue is due to protocol mismatch between old client / new server I think.
