It seems that they all think that the updating/upgrading is easy.
I hope that while I pointed out the difficulties of upgrading Windows, I wasn't suggesting that Linux is perfect. I'm amazed at how well I did with this distro with "testing" enabled, but I got bitten in the end. Of course I did.
After writing my replies, I listened to some "TWIT" podcasts and heard people having totally different problems with upgrading and updating.
I figure updates, upgrades (especially business software) and snakes have much in common. Experience and good practice avoid the worst, but if you are not apprehensive then you simply haven't met the right situation yet.
The good points here are that:
1. You will have made a recent liveCD (DVD) and of course have tested that it actually works because that is as simple as putting it into a drive. Back in the day, backups were on LOTs of floppy disks or a tape drive. And the only way of testing was to reinstall onto a very expensive hard drive. So often backups weren't tested until too late. Once you've reinstalled and failed, you've overwritten vital data.
2. Home is on its own partition!
Now imagine yourself next to a defunct business computer. But you have made an image which is on an external drive. So do you re-install the computer drive? In these days of cheap drives, there's no real problem. But there was once. I've spent more than one night recovering data onto my own reformatted drive before doing a re-install from a tape drive. Failure to get the business server up by morning was a loss of lots of loot for my friends.
So forgive me if I gave the wrong impression: I figure all upgrades are hard.
