however is that Debian/Ubuntu do have a fairly well-tested mechanism in
place for upgrading libraries etc. when necessary, while Slackware- at
least when I last looked- has to be reinstalled which is significant work.
I wouldn't know about OS upgrades - even for Ubuntu. I *never* upgrade an OS,
but rather install from scratch. With my current partition layout, no matter
which Linux distro I use, it is very quick and easy to do.
Using a 250GB disk, I normally have four partitions. One swap partition and 3
file partitions. Change sizes to fit your needs.
swap 2GB
/ 25GB
/home 128GB
/opt 95GB
So when a new release of Ubuntu or whatever Linux distro comes out, I backup
the /etc directory to my home folder. Then simply reinstall the new OS using
the above setup. The root (/) partition is the ONLY partition I format during
the new installation. I can then copy back the config files into /etc, or
modify the new ones, using the old ones as a reference (I prefer the latter).
The /opt partition contains things like Adobe Reader, Firefox beta, Lazarus,
FPC and other git repositories - thus no need to reinstall them, after a new
OS install. The /home/<username> is used for downloads, documents or any
project source code I work on. Again, by simply creating a user account in
the new OS, with the same name as before, my desktop and all application
settings are automatically correct. All other data are intact too.
This setup has worked very well for me for the last 5+ years, and takes
roughly 30 minutes to install a new OS version. I once did a Ubuntu upgrade
and it took well over an hour, and lots of issues - so will never do that
again.
Strange. The painless upgrades is why I switched from OpenSuSE to Ubuntu.
Never had any troubles, and I am doing this since 8.04.
But as always with computers, "your mileage may vary..."
Michael.
