I just upgraded 18 servers running mission critical network infrastructure and services for a research group of 150 people. Everything went without a glitch. Some of the servers have been continuously upgraded since OpenBSD 5.4. That is a solid 5 years which is a typical lifespan of a production server. Just as a comparison, I am still afraid to upgrade dozen or so file servers and jail hosts running FreeBSD 11.2 to 12.0 in-spite of root on the ZFS mirror and beadm. I typically wait at least year and a half after initial release of Red Hat to do fresh re-installation of our computing nodes. Red Hat as you know doesn't support upgrade between the major releases. Ubuntu (deep learning guys love that crap) upgrade from 16.04 to 18.04 should not be attempted on the production server. On the top of it network stack on Ubuntu 18.04 is completely broken (at lease running as Xen DomU. I was too afraid to try on our AWS instances). > I tried to update a VM (stock setup) with a 10 GB disk from 6.4 to 6.5 > and thus it seemed that booting from the 6.5 DVD will do the trick. > Sadly the installer never checked the avalable space , but just started > to do it's stuff until reporting that not enough space is available. > > Why did the installer allow installation despite the available space is > low ( even windows checks available space :) )??? > > Why should the end-user delete old unnecessary/problematic files ? Because Theo's misplaced his crystal ball and without it, it's impossible for him to tell which of your files are old and unnecessary and which once are your local modifications and important data files. > Usually we do have package management system to take care of that (or at > least to rename those files in case we really need them). > > For me, system upgrade is a very complicated and error prone > procedure. > Just move on.
