[ec2-beta] howto user-data scripts

[Wouter Samaey]

Hi,

I've known there has been talk about the user-data scripts before, and
I've read all I could find, but still don't understand how to use this
feature. I believe Eric Hammond also stated this is pretty
undocumented.

Could someone please write a simple tutorial for this?

My goal would be to write different scripts that would configure the
instance on first boot (not reboot), as a replacement for creating own
AMI's. This way I could keep using official AMI's, and upgrade as
newer versions come out.

I'm using EC2 right now, but have never used the user-data before.

Thanks in advance
