Description

The content of user-data API should be stored properly, not to be continuously requested line by line.

On Alibaba Cloud, the user-data API (URL: http://100.100.100.200/2016-01-01/user-data ) responds the cloud-init config file in a multi-lined plain text way, and the first line is #cloud-config( or #!/bin/bash ) , which caused the URL will be requested later becomes http://100.100.100.200/2016-01-01/user-data/#cloud-config, the metadata API will respond the same content as before, so the recursion will never end.

Ohai Version

I'm using GitLab: GitLab (latest, 15.2.2) -> chef (17.10.0) -> ohai (17.9.0)

Platform Version

VMs on Alibaba Cloud, but I think those Clouds having the same user-data responding logic will have the same issue.

Ohai Output

I'm sorry I'll put the output of GitLab here.
