Installed AIX puppet on three test servers running 5.3, 6.1 and 7.1. All went well until I tried a manual puppet run and got the following error.

If puppet is unable to read the current crontab it will assume an empty one. As a result the agent will then add the puppet managed entries to the empty list of cronentries and then writes the modified crontab. As a result you will loose all your unmanaged cronentries.

Any help on this? Even if it is caused by some problem with server config, it should not continue to write over crontab if the crontab -l fails.

I can reproduce it every time I run "puppet agent --test" from the command line. Strangely this command runs fine when executed from cron.
