If your current kernel doesn't lack in functionality or have security issues there is no need to upgrade. Just because a new kernel is released that doesn't mean you install it!!! | | On Oct 16, 1:13 pm, dbee <[EMAIL PROTECTED]> wrote: |> I want to be able to keep my system up to date with regards to |> packages and kernel updates.

The truth of the matter is that you don't need to update ALL the packages unless there are security fixes or added functionality that you need. Putting these things in the crontab won't make your system bulletproof. This is not like antivirus software or the go out and grab all updates mentality. You should inspect the updates and not treat your server like a Windows desktop. |> 2) Should i stick that in root cron or user cron ?

This is similar to having 2 root accounts so if the user debee gets compromised, its as good as having root. |> 3) What should i do about kernel upgrades ?

I'm 99.9 percent sure that you don't need to constantly upgrade the kernel on that system.
