rescue media fails to boot
acronis true image 2016 build 6571
built rescue media ( both cd, dvd, and usb stick ) and all fail with the same error.
right after choosing acronis from the boot options it says "loading please wait"
then comes back with
udevd-work mknod /dev/vcs2 7:2 failed no space left on the device
I am not sure what device it is talking about since the cd should not need space and the drive on the machine has several hundred GB of free space. also there is 16GB ram on the machine.
see the attached picture for full error details.
any ideas would be very helpful.
