Is there a transition guide from 4,5,6 distros to 7 distros? Something like "if you used to do XXX with init, this is how to do XXXd with systemd", for all the bits of the distro that made large behavioral changes with RHEL7/CENTOS7/SL7 ?
The transition from SL6x to SL7x is challenging for those of us who set up our Linux environments with init, Gnome2, etc. years ago and copied them mostly intact from distro to distro (and turned off selinux, which was easier than learning it). I accept that with SL7 I must learn systemd, selinux, new versions of applications such as firefox, evince instead of acrobat, and how to compile and maintain mate because gnome3 designers favor glitz over preserving procedural workflows. The sparse documentation I've seen explains RHEL7 in terms of itself, not in terms of transitions, especially for applications added by customers on top of the distro. The libraries changed also, so I will be porting, rewriting, even abandoning some of those applications. As much work as this is, it is better to do it now, before more applications are added. So - are there any documents, useful magazine articles, websites, that make the transition less difficult, that explain how to redesign procedures and port applications? Keith P.S. Getting angry and vengeful is tempting but not productive. Decades ago I worked for Tektronix, when the flagship 7000 series of oscilloscopes was replaced by the new and very different 11000 series. Sales of both series plunged when customers realized that Tektronix would not support their workflows in the future, and bought predictable lab and production instrumentation elsewhere. I wonder if a similar sales plunge is happening at Redhat now? I had such hopes for Ubuntu/Canonical, but they have the same disease. -- Keith Lofstrom kei...@keithl.com
