watchall.sh forwards serial output from Barrelfish to your console. It 
is not required to boot the SCC and only provides a convenient way for 
output from Barrelfish, so you can leave it out.

In order to make it work without root privileges, you probably have to 
give proper privileges to the SCC UART device files in /dev that 
watchall.sh is trying to access.
