I want to do a SysUpgrade of my EspressoBin Board actually runninng 18.06.01 to the latest 18.06.02, but I have made an extroot overlay.
Do will I to plan a fresh new install from scratch, instead of a magic sysupgrade with luci ?
What about upgrade with sysupgrade or with luci when using an overlay for extroot ?
Is it supported actually or is it impossible in anyway ?
I have the same setup and I think I consulted the same link when I was trying to find a way to upgrade the image. I have performed a couple of upgrades without any issues with the following procedure.
thanks again,
It works fine, but we still need, on the espressobin board, a real upgrade because we have to make "from scratch" install instead of "in place" upgrade".
For remote management and easy update like standard OpenWRT devices...
The overlay look also a case of complicate upgrade and cannot be made without some tweaks.
If you have many devices to manage, perhaps a custom build that mounts your external file system rather than the default of using the "split" of the boot media.
Do you want to say that I may use a custom build, and lost all kmod support, only for a partition map change ?
Or is there any other technical solution I do not know, to get this possible ?
Another question looking right in the subject; is the rootfs_data partition naming possible to silently and fastly usable for an external USB/SD/HD partition shema ?
If I define a partition map with BOOT and ROOTFS (from the OpenWRT standard system image) and I just add the rest of the support with an empty partition named rootfs_data, will this third partition being used as the rootfs_data overlay default ?
