=== Begin SRU Information ===
- impact on users: 'apt-get upgrade' fails if python2.4 is installed. This is because the installation attempts byte compile for all installed python versions, but some syntax is not 2.4 compatible.
- how the bug has been addressed: The EC2Init class had python 2.5+ syntax ['class EC2Init:()']. This was replaced with python2.4 compatible syntax by removing the '()'.
- patch is available at: http://bazaar.launchpad.net/%7Esmoser/ubuntu/karmic/ec2-init/karmic-updates/revision/37.1.1
- regression pottential:
There was no other dependency on python2.5+, other than the syntax listed above. As such, with the fix, the byte compile succeeds. The code has been quickly tested to even run with python2.4, although this is not strictly necessary as /usr/bin/python will not be python2.4 in karmic.
TEST CASE:
- start ec2/uec instance (ami-1515f67c is current karmic us-east-1 GA -- 20091027.1.)
- sudo apt-get update && sudo apt-get install python2.4
- 'apt-get install ec2-init' will fail

This is not an issue with cloud-init (which replaced ec2-init) in lucid.
