system broken

[Daniel Golle]

Thanks for testing and reporting back.

I have fixed a bunch of config migration issues which would lead to
ubus not starting up (and system hanging in preinit).
This should have been fixed by
commit de7ca7dafadfd650d031e0379ce0c002868d5936

base-files: merge /etc/passwd et al at sysupgrade config restore

Can you try if that resolves the issue?

If you didn't preserve configuration during sysupgrade it will probably
not resolve it and have to look for other causes...


Cheers


Daniel

After this, system does boot, but password is reset to no password. I don't know if other settings are reset too. ubusd is not started. uhttpd fails to start, because ubus socket isn't available. If I apply a previously saved backup with 'sysupgrade -r ...' and force a reboot, system starts, but tries to initialize a ext rootfs, which doesn't exist, and hangs in the boot process. At this point, I've to do a recovery via uboot. My router is a tp-link Archer C7.
