It doesn't make more then what I said in any case, so take the sed, the
obsolete tail -1 and the grep out and ready.

Are there cases there a dynamic DNS don't want to be used ? which ? From what
I have read on the net, if the option usepeerdns is used the variable
USEPEERDNS is set, so this could be used, am I right ?

mv -f /etc/resolv.conf /etc/resolv.conf.tmp
cat /etc/resolv.conf.tmp | awk '{if(!/nameserver .* # ppp temp entry.*/) print
$0}' > /etc/resolv.conf
------
print all lines that does not contain the pattern
nameserver ........... # ppp temp entry
to /etc/resolv.conf
chmod 0644 /etc/resolv.conf
------
shouldn't using cp instead of mv preserve the rights of /etc/resolv.conf ?
