Title:
namespace collision on url kernel arg results in downloading iso
multiple times
Status in cloud-init:
Triaged
Status in casper package in Ubuntu:
Confirmed
Bug description:
As listed at https://discourse.ubuntu.com/t/netbooting-the-live-
server-installer/14510/135
When attempting a netboot, we can end up in a situation where cloud-
init downloads a full iso, only to decide that the first few bytes
aren't the expected header and to ignore it.
I suggest an enhancement where a small amount of data is downloaded at
first, we check this data for the required #cloud-config, and then use
that info to decide to continue to download the file or not.
