Possible bug in AppendIfNoLineMatching under solaris 9?

[Paul Dlug]

I have the following in my cfengine config:

any::
   { /etc/mail/aliases
     SetLine "root:$(tab)root_grp@ridge.aps.org"
     AppendIfNoLineMatching "^root:[[:space:]]*root_grp@ridge.*"
     DefineClasses newaliases
   }

Under FreeBSD 4.8 with cfengine 2.0.3 this works and properly appends 
"root:   root_grp@ridge.aps.org"

Under Solaris 9 with cfengine 2.0.6 this appends:
^root:[[:space:]]*root_grp@ridge.*

And will keep appending every time it runs.

This doesn't seem to be a problem on another solaris 9 host I have, 
only difference being the above host with the problem is at a newer 
patch revision. Both hosts are running the same build (built a package 
of cfengine on the first host (one with the issue) and installed on the 
other host (not having problems)).

Does anyone have any suggestions as to what may be wrong?


From cfagent -v -q:
Begin editing /etc/mail/aliases
Set current line to root:       root_grp@ridge.aps.org
Appending [^root:[[:space:]]*root_grp@ridge.*]
End editing /etc/mail/aliases
