redirecting stderr is good but will also discard other possibly helpful error 
messages if something goes wrong. You can simply avoid this particular one 
with something like this :

tar -cf archive -C/ .

another trick is to redirect the whole script to some log file (or /dev/null 
if you're fearless) by putting this at its beggining :

LOGFILE=...
exec > "$LOGFILE" 2>&1
