CentOS - Mar 2006 - Something keep modifying cups config

Hello,
I have the following line in my /etc/cups/mime.types uncommented :
application/octet-stream

so that Windows machine which can use the printer driver can print through the 
cups printer set up on a CentOS box. 
But something keep changing the file by commenting out the line. So sometimes 
printing from Windows would stop working and it the cups error_log I see:

E [21/Mar/2006:12:58:34 -0500] print_job: Unsupported format 
''application/octet-stream''!
I [21/Mar/2006:12:58:34 -0500] Hint: Do you have the raw file printing rules 
enabled?

All I need is usually just uncomment that line in /etc/cups/mime.types and 
restart cups. 

So I couldn''t figure out what keeps changing the files. Am I not
supposed to
edit the file directly, or am I missing something else here ?

Thanks for any help.

Is this cups-config-daemon? We always do

/etc/rc.d/init.d/cups-config-daemon stop
chkconfig cups-config-daemon off

That would not be a Deskjet 1020 printer, would it ?

I have this exact problem on a machine with that.

Tried disabling cups-config-daemon, hal and a few others, to no avail.

Finally, I found a way to workaround the problem:

# chattr +u /etc/cups/mime.types

You have system-config-printer package installed.  Which believes it has 
complete control over Cups configuration.  Each time cups package is 
updated, it will use system-config-printer to regenerate configuration 
file, overwriting your changes.  Some other processes may trigger it 
too.  If you are manually setting Cups configuration, simply deinstall 
system-config-printer and all should be fine.  If you are using GUI, 
don''t touch the files with vi editor.

Well, except there doesn''t seem to be anyway to do this from 
system-config-printer.
