Puppet users - Jan 2013 - Augeas file line edit please help

what i thought would be a simple edit using augeas is turning out to not be 
so straight forward, can anyone please help ?

the plan is to edit sendmail.cf and change the default DS to 
DShostname.domain

class mail {
      $key = DS

      service {
            ''sendmail'':;
      }
      augeas { "sendmail.cf/$key":
context => "/files/etc/mail/sendmail.cf",
 changes => "set $key mail.hostname.domain",
notify => Service[''sendmail''];
}
}


debug: Augeas[sendmail.cf/DS](provider=augeas): Opening augeas with root /, 
lens path , flags 0
debug: Augeas[sendmail.cf/DS](provider=augeas): Augeas version 0.9.0 is 
installed
debug: Augeas[sendmail.cf/DS](provider=augeas): Will attempt to save and 
only run if files changed
debug: Augeas[sendmail.cf/DS](provider=augeas): sending command
''set'' with
params ["/files/etc/mail/sendmail.cf/DS",
"mail.hostname.domain"]
debug: Augeas[sendmail.cf/DS](provider=augeas): Skipping because no files 
were changed
debug: Augeas[sendmail.cf/DS](provider=augeas): Closed the augeas connection

might be easier to just use sed in a exec statement to replace all 
occurances of DS with DShostname.domain 

Ex:
sed ''s/DS/c DShostname.domain'' /etc/mail/sendmail.cf

There''s no Augeas lens for sendmail.cf files.  From Puppet 3,
it''ll now
warn you if using context and a file wasn''t loaded.  Otherwise check in
augtool with "print" to see if the file can be loaded.

Maybe use stdlib''s file_line type?
