Script to update 2.9.x ISO to use Linuxcnc Version 2.10 (master branch)

I updated above. Did it work?

Yes it works. But my ethercat system now fails, no slaves detected.
Upgraded bot ethercat mater and linuxcnc so don't know what's wrong.

EDIT: was unrelated. My experimentation with network interface left the interface not UP after reboot. Simply ifup enp2s0 and it works again.
I am back on 2.9. Have a lot of chores to do now, I'll pick this up in the evening.

EDIT 2: It works. I did get an error when starting 2.10 from Qtvcp, due to that [KINS]COORDINATES was missing. After I added that in the ini file  there was a conversion, a restart, and then it worked again.
