Why would you do that? I have Linux setups at work that are 5-6 years old that have never been down other than for kernel upgrades and power outages, and that are still as clean as can be. Many of our systems have been running 24/7 with no downtime for 3+ years.
If you need frequent total reinstalls with Linux you're doing something very bizarre to it.
Exactly my thoughts. Reinstalling is the easy way out, try to fix it, you might learn something.
My main Debian sid install is more than 4 years old and I never had any mayor problems, it's running 24/7 and it's rocksolid. I only reboot after kernel upgrades.
I even think that almost any Linux distro is easier to install and maintain for the average Joe/Jane than any of the Amiga clones around (or Windows).
