Augeas file line edit please help

[kdo]

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

[kdo]

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?
