Hi,
I have customized my Fluksometer by installing additional packages on it from the OpenWRT repository. For instance I have bridged the wired LAN and wireless LAN interfaces of the Fluksometer to make the device a wireless access point, and created an NFS mount from the Fluksometer to my NAS to increase its storage capacity (CIFS doesn't work). Now I don't want to miss the new functions and bug fixes of the new Flukso software, but I also don't want to have all my customizations overwritten everytime I update the device with new Flukso software. Is there a way to have only the Flukso packages updated (together with their prerequisites) rather than flash the entire firmware image?
Greetings,
SergeDV
OpenWRT uses the read-only squashfs as its root file system. Any file changes you make are written to an overlay jffs2 file system. This includes package updates. Any release will come with changes to the root fs. Most of the time the kernel will be updated or its config options will have changed. That's why we always download and flash the kernel and full root fs during a firmware update.
You could copy the /overlay contents before an upgrade and then selectively copy your config back to the FLM after the upgrade. Please note that changes to /etc/config will always be preserved.
