cfengine 2 migration issues

[Ruben van Staveren]

Hello all,

At RIPE NCC we have deployed a network of 60 so called Test Traffic
Measurement boxes (http://www.ripe.net/ttm/) and are currently in the progress
of upgrading our network from cfengine 1 to cfengine 2. We have encountered a
few peculiarities which weren't there in the previous versions.

cfengine 2 is now installed on our FreeBSD 4.x based Test Traffic Measurement
Testboxes, with the following remarks:

- We are using version 2.0.6 instead of the latest version available because
  the grammar in the .l and the .y files changed in 2.0.7, causing harmless
  but noisy error messages to appear when using a SetOptionString

        address@hidden:102] /tmp/cfe2/cfengine-2.0.7/src/cfagent -n -DCRON -f
        /home/ttraffic/config/cfengine.conf 
        cfengine:tt97: Regular expression error 14 for 
        cfengine:tt97: empty (sub)expression

  It could be that the BSD implementation of the regular expression library is
  more strict and this error is not triggered on other platforms.

- Separate binaries for root and a non privileged maintenance account have
  been installed, this is due to the fact the cfengine status directory
  (LogDirectory) is not run time adjustable anymore. See
  http://mail.nongnu.org/archive/html/bug-cfengine/2003-11/msg00018.html
  what was wrong with the cfengine 1 way of doing things ?
  We use a setup where cfengine is run from cron, and not from the cfengine
  daemon.

- There seems to be a problem with the umask setting, we have to readjust
  permissions on files generated from programs under cfengine 2 control which
  was not needed in cfengine 1


Kind Regards,
        Ruben van Staveren
