Every time it gets re-written, I run into the issue here: http://samba.imasd.elmundo.es/samba/docs/man/Samba-HOWTO-Collection/CUPS-printing.html#cups-raw regarding 'application/octet-stream' getting commented.

So I figured out that cups itself is overwriting the config files following some sort of cups error when you try to print to a printer that is not online.  That's not very convenient!

Here is a snippet from /var/log/cups/error:

What's with the 'Saving printers.conf...'!?
It seems to clobber my Listen/Browse statements and change mime.types possibly to some default settings?

cups-1.1.23-15.1
