reproducer userdata cloud-init script

Description of problem:
userdata cloud-init script fails to install httpd because httpd scriptlets fail to execute. 
It seems some filesystem service might not be ready at the time user-data script is executed as the error codes suggest (127 file not found).

See the attachment for the user-data script; Additional info section gives a screen log of the situation.

Version-Release number of selected component (if applicable):
ami-f1031e85; Official Fedora AMI - Fedora-x86_64-19-20130627-sda

How reproducible:
always

Steps to Reproduce:
1. init the launch of ami-f1031e85 in ec2 (eu-west-1)
2. in instance details, give the attached script as user data script (load from filesystem)
3. launch the instance
4. log-in and cat /var/log/httpd_userdata.log

Actual results:
file-not-found scriptlet errors prevent userdata-based installation of httpd. A filesystem service might not be running at the time userdata scripts are executed

Expected results:
it is possible to install httpd via userdata cloud-init script
