Re: adding lines based on field match (or lack thereof)

[Andrew Mayhew]

I came up with a solution which uses a similar methodology that you
described below.  In our situation we have very few locally specific
accounts on machines and so we allowed the local adminitrators to deal with
those outside the cfengine realm.  Our config looked something like this:

editfiles:
  any::
    { /etc/passwd
      SetLine "someuser:x:42:42:name:homedir:shell"
         AppendIfNoLineMatching "^someuser:.*"
         ## repeat for all the accounts listed in passwd.global
         
         SplitOn ":"
         ForEachLineIn "/etc/passwd.global"
                ReplaceLinesMatchingField "1"
         EndLoop
    }    

Only the passwd.global file would actually have the encrypted password, so
that account would not be active until the for loop had been processed. This
also ment that we only needed to change the password in the passwd.global
file and not in the cfengine configuration file.

Hope that helps somewhat.  Still not necessarily the most pretty solution,
but one that works.
