[OpenWrt-Devel] Help with SysupgradeNAND

[Andre Valentin]

Hi!

I also noticed after upgrading that routers with jffs2 in ubi (rootfs_data) are not
supported anymore. The jffs2 is not mounted after an upgrade,
resulting in loss of configuration. I had to clear rootfs_data
to be able to mount it again as ubifs. That's okay if you know it!

I noticed a second issue. hostapd (running in some kind of dfs loop) was not killed
by sysupgrade nand. That resulted in breaking the upgrade. System rebooted with old image.
I personnaly added a check in sysupgrade if it runs below upgraded and if
that's true, I kill _all_ processes. If interested I could publish the patch.

A third point is the upgrade itself. I the rootfs image grows, and rootfs_data
has all the remaining space aligned, it will not work because rootfs cannot grow.
Perhaps rootfs_data should always be recreated in the update process. If interested
I could also supply a patch.

Kind regards,

André
