If i want to do an upgrade, the most "secure" way to do that would be by DVD's, right? because if I do upgrade through FTP and the net goes down that would screw things up enough to not be able to restart the system... or?
Hi guys...been away for a bit with medical problems with the old bum back. Back surgery is not fun. Just say no.
If you are worried about an internet connection through FTP, either on your end, or worried about a server end, then you should go with the DVD. At least with the DVD you can do an md5checksum to make sure every bit of data is ironed out, and nice and smooth. With FTP, you have an increased "risk factor." There are a lot of things that can go wrong over a TCP/IP connection that you will have no control over.
What you could always do, if you are in the mood to experiment with the different methods that a Linux distro has to offer, is always back up. If you have a spare drive or partition laying around somewhere, just use dd to dump it to an open partition or a free disk. Use dd again to back up your boot loader, and then go from there. With a boot floppy you can always edit the disk with your working version of Linux, and switch the options whnenver. Linux gives you that flexibility.
Explore the possibilities. If you are unsure about upgrading using apt, then give it a whirl. Just make sure you back up your existing installation in case you botch something. Try it by adding a downloaded DVD to your sources.list file and do a routine apt-get dist-upgrade. If it fails, retrace. You can always reformat the drive and dd your back up (and bootloader) to its original location. If you just want to check certain changes to the OS versions, mount the cd and use the diff | sort commands (with whatever options you need...use the man page) to check the differences. You could also use apt-cache policy to check these as well. Remember, the command line is just that in Linux: COMMAND, and you are the commander. I went from FC4 to FC5 using a variation of this model, and executed it perfectly and learned a lot by watching the process, and by reading error codes.
I never wrote a script for this, but since I am able to actually sit in a chair and type now, I will be more than happy to try to write some stuff for you. If you know how to use fdisk (linux..not that P.O.S. that is laughingly called FDISK in windows) and a few basic commands, and know how to direct input and output using BSH or BASH, and you know how to read a man page, and think, you should be fine.
Just back up everything, and use your boot disk. Try out differnt methods, until you find something that you are comfortable with. This is Linux. Nothing is etched in stone, and there is no "wrong" way to accomplish your goals.
