[OpenWrt-Devel] sysupgrade --force broken in master?

[Hannu Nyman]

I noticed that the sysupgrade script seems to fail to force a sysupgrade.

Trying to sysupgrade WNDR3700v2
from  ar71xx  r11464-cabaaf06fe
to  ath79  r11469-db09335848


I tested with console sysupgrade, and that failed, too. Router reboots the 
current firmware without flashing. The ssh console output shows how the 
router starts the sysupgrade and notes "--force" but then no actual 
sysupgrade happens, instead the router reboots and returns to the existing 
firmware.

I do not current have serial console connected, so this debugging below has 
been done just via SSH console
