I'm a bit confused now... why do you mount "/overlay" and then "/" from an external device?

What is the output of "mount"? Any errors during boot on "logread"?

Here is the extroot command I use. Just did it recently and it worked perfectly.


mount /dev/sda1 /mnt ; tar -C /overlay -cvf - . | tar -C /mnt -xf - ; umount /mnt

block detect > /etc/config/fstab; \
   sed -i s/option$'\t'enabled$'\t'\'0\'/option$'\t'enabled$'\t'\'1\'/ /etc/config/fstab; \
   sed -i s#/mnt/sda1#/overlay# /etc/config/fstab; \
   cat /etc/config/fstab;

and remove this

Your device is not mounting any external filesystem... have you installed all the required packages after the upgrade?

Glad that worked!

I can't really help you with the wifi radio issue, but I'd recommend opening a new thread for that. Be sure to include the relevant details (config files, scripts, the specific symptoms, what works/doesn't work when you don't use the script, etc.).
