Device not mounted after sysupgrade (UUID mismatch) about openwrt-auto-extroot

[arrmo]

Yes, agreed - just not sure how to make that request. But it seems that an upgrade shouldn't break Extroot, agreed?

Thanks!

thanks for recording the issue!

so, the /etc/.extroot-uuid thing is a safety measure to avoid confusing overlays over extroots (it's the UUID of the firmware's root partition, recorded on the overlay at creation time). (the log message is very confusing, though)

would it be wise to automatically delete it in case of a mismatch? what else could we do if not that? create a FAQ or some kind of doc entry about upgrades?

unfortunately i won't have much hacking stamina to look into this now, but patches are welcome!

Hi,

Perhaps a dumb question, but ... why not do this automatically? I admit, I'm having to manually do this and reboot every upgrade - it is a pain. And if extroot is enabled (in /etc/fstab), why not do this?

Thanks!

to be honest, i never played with openwrt upgrades, and i think this^ above is a vanilla openwrt issue, right? i mean, is there something we could do besides reporting a feature request to the openwrt guys?

fix this feature it is annoying to remove .extroot-uuid all the time and in particular as I do a new build every week from the master

this is an openwrt issue, unrelated to this project, so i'll close this one. if you want to pursue it then report in the openwrt issue tracker.

the openwrt wiki suggests that it's not supported: http://wiki.openwrt.org/doc/howto/extroot#old.notes

and here's a description on how to fix manually if you nevertheless attempt an upgrade: https://wiki.mbirth.de/know-how/software/openwrt/sysupgrade-with-extroot.html
