@64bitfury Eventuelly found the time to proceed on the wiki article. Find information on your question here: https://wiki.fogproject.org/wiki/index.php?title=HTTPS#Custom_CA_and_certificates
Please let us know if the instructions are clear (and do work)! We can only improve things as much as we get feedback from users. :-)
We have another report on this: https://forums.fogproject.org/topic/14249/image-size-of-the-client-in-fog-does-not-match-the-size-of-the-capture-in-hard-drive
@Ben-Acheff Still waiting for you to provide the contents of d1.minimum.partitions from your image.
