Red Hat Bugzilla – Bug 800439
Add capability to run user scripts from userdata in RHEL AMIs
Last modified: 2012-10-31 05:12:49 EDT
Request from Amazon:
We have a request from a customer to have RHEL AMI output the ssh fingerprints to the console on boot. This allows our customers to verify that the host they are ssh'ing to is the same host that is in their account in the console. We also recommend this to customers in the EC2 User Guide:
The customer would have setup a script to output these himself but the RHEL amis don't currently have a mechanism to run user scripts from the userdata.
Would like to target this for any future regions (add it to all AMIs) and for existing regions, only add it to new versions of RHEL.
This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux release. Product Management has
requested further review of this request by Red Hat Engineering, for
potential inclusion in a Red Hat Enterprise Linux release for currently
deployed products. This request is not yet committed for inclusion in
Note that this bug is solved with use of the cloud-init package.
According to e-mail communication cloud-init will not be available for RHEL5 at all. Supported will be only RHEL6+ distros.
