I'm only beginning to use *buntu, so please excuse any Fedora-centric sounding questions. Also, this is from the perspective of my personal machines, not network full of users.
When I upgrade to a new major release, I typically do a fresh install. This means saving my personal stuff to someplace else, doing the install, and then cleaning out the new directory that was made for me in the install, filling it with all my old stuff, and then hoping I haven't introduced any incompatibilities. Ostensibly, the release notes should help me out with that, but I still worry. I've never had a real problem with this, but it always concerns me.
After that the real fun begins, with the customiizations I use. For example I use secure versions of dovecot and postfix. I have to go in and rebuild these each time, with the fixes for ssl and tsl. I have my personal and root certificates that go with those, and iptables set up the way I like it, and other things.
Of course, I keep a list of these things aand go through it each time, but it sort of seems like something the computer ought to do. I was wondering if there was anything like the configure perl script we all use for installations, that I could run right before I upgrade. It could do a chkocnfig, for example, and see dovecot and postfix turned on, and sendmail turned off. And then it could go and gather all their configuration files in /etc or whereever and bundle them up for me, gather everything into a tarball with a more or less annotated list of things to do - in the "more" case, it would make an effort to see if my configuration files would still work with the latest version.
So my question is, is there a tool that does this or something like this, or something else that I am missing that will make these upgrades all quick and easy?
