I meant that we should leave ec2-init behavior as it is right now, with
'run-once-ever' for ec2-set-defaults.

'<ami_id>' was referring to the current ami_id of the image being
rebundled. I just wanted to acknowledge that if you remove the '.ever'
file, and then reboot the instance any local changes you've made are going
to be blown away in *this* instance. Its probably not a big deal. But,
to demonstrate, something like:

$ echo "LANG=en_CA.UTF-8" > /etc/default/locale
$ rm /var/lib/ec2/ec2-defaults.ever
$ do-the-rebundle
$ reboot
...
$ cat /etc/default/locale
LANG=en_US.UTF-8

After 'reboot' on *this* current instance, /etc/default/locale would get
rewritten because ec2-set-defaults would run, because there was no '.ever'
file stopping it from running. I incorrectly thought that touching the
'.<ami_id>' file would prevent the run after reboot.
