One more tidbit... if I use busybox awk here, I get failures, otherwise I
don't (the other invocations of awk in this script work either way):
# This is a convenience function to make sure that user input is
# looked at as a fixed string when being compared to something. $1 is
# the input; this behaves like 'grep "^$1"' but deals with regex
# metacharacters in $1.
_ovs_vsctl_check_startswith_string () {
awk 'index($0, thearg)==1' thearg="$1"
}
The extent of my awk knowledge is knowing where the name comes from, so
I have no idea what might causing the problem here or what alternative
implementations might be worth trying...

Lance
