ConfigDrive with symlink inside breaks cloudbase-init

edit

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.
