Just FYI, what you are doing here is running 'echo 0' as root, but you
are using the shell to redirect the standard output to
/sys/class/rtc/rtc0/wakealarm, because the shell process is
responsible for the redirect and is running as a non root user you get
the permission denied error.

This subtlety has caught me out in the past!
