-====== CCGX - Developer migration notes for swupdate ======
-(draft!)
-==== What is swupdate? ====
-swupdate is the name of the tool we use for image updates. Image updates? Yes, previously the CCGX firmware updates were all done with packages. Not anymore, finally!
-For the advantages, see: [[https://github.com/victronenergy/venus/wiki/swupdate-project#new-features-for-in-the-change-log|swupupdate-project#features-for-in-the-change-log]].
-To learn more background and details, read the rest of that same page.
-==== What has changed for developers? ====
-  * the set-feed.sh script is now here: ''/opt/victronenergy/swupdate-scripts/''
-  * the root-password will be removed after every update.
-  * ssh keys will be maintained: so that is what you should use!
-  * everything not in the /data partition will be gone after an update
-==== What happens during this manual one-time upgrade of a CCGX? ====
-  - It saves the contents of the old /data partition
-  - Formats most of the nand storage, without touching the bootloader, and creates several volumes: kernel1, kernel2, rootfs1, rootfs2, data, etcetera.
-  - Restores the data partition on the new partition
