I am using Ubutu 9.04 for a production application where it needs to run the latest subversion client, run a bunch of scripts to develop reports based on subversion respositories, and uses crontab to report results of the nightly jobs. First time I used this, I got a report from crontab that I wan not expecting (and it new how to send to me using sendmail via my alias to my real email address). Sendmail setup was straight forward and just works. Now that the box is in production, I get a full log of the crontab job including errors that might have occurred, primary due to connectivity errors. I used to run all this on Redhat 8 Server where it was originally build and did not get anywhere near this level of reporting (like no reporting)! And with 9.04, I have this box fully loaded with all the mono tools and a full LAMP environment. Lovin it!
