ConfigDrive with symlink inside breaks cloudbase-init

Hi guys,

I just ran into an issue, I'm using ConfigDrive as MetaData service, the ISO was detected but cloudbase-init was not able to extract it (cf. [1]).

The reason is that my ConfigDrive had a symlink 2015-10-15 pointing to latest and it seems to not be very appreciated on Windows (my Windows knowledge is very poor). After removing the symlink, cloudbase-init was running as expected.

There are two solutions (IMHO):

  1. Let's cloudbase-init detects symlinks and handle them properly
  2. Add a note into the documentation saying that there should be no symlinks into the ConfigDrive

Hope it helps.

Can you please post a cloudbase-init log on or similar service and link it here? Thanks

To make it easier to debug, it would be great if you could give some more information on your setup.

From the logs, I see that you are using something similar to Ironic?

Thank you,

Yeah I'm running Bifrost (Ironic standalone), ConfigDrive ISO are generated manually with genisoimage.

For some compatibility reason with cloud-init I need to have 2015-10-15 version in the ConfigDrive which is pointing as a link to latest (to avoid data duplication).

Just to be clear, I solved my issue by duplicate data (which is not the best but acceptable for now). I opened this question as KB for people who have the same issue.

Let me know if you need more information.

Thank you,
