Bug#910801: cloud-init: cloudinit might delay startup by a long time if time is stepped during boot
Package: cloud-init
Version: 0.7.9-2
Severity: normal
Dear Maintainer,
During testing of cloudinit, got a clock adjustment while in wait_for_url() function
https://salsa.debian.org/cloud-team/cloud-init/blob/debian/0.7.9-2/cloudinit/url_helper.py#L269-371
This caused the timeout for the EC2 data source to be more than 1 hour.
