cPanel regularly overwrites awstats.conf

[Funky Rob]

I like to modify /usr/local/cpanel/etc/awstats.conf to add a skiphosts line.

The problem is that very regularly, cPanel overwrites this file.

I've tried chmod -w but this doesn't make any difference.

I've tried chattr -i but my system doesn't seem to support this command.

Is there anywhere else I can put global awstats configuration options?
(Or any way of stopping cPanel overwriting this file?)

thanks

Rob
