Sigh. Yes, I know you have to go through 17 to get to 18, Mr. Harald. And, no, it's
not just a matter of
"following instructions." In fact, almost nothing that requires significant
technical skill is just a matter of
"following instructions." Arrogant savants forget the fact that they paid a
lot of dues learning the little tricks
that *aren't* in the instructions. Your tell, for instance, is that you brag about
upgrading 20 machines from F9
to F18. You may not be willing to admit it, but I suspect *somewhere* in there, there
were a few gliches. But,
because you have done it a bunch of times, you know how to deal with them. That's
very different that doing it for
the first time.
2006 i switched from one day to another completly to Fedora
this was short before FC6 was released, so my very first "no fallback machine"
was installed with FC5 and two days later upgraded to FC6 and while 1.5 years
later i started with production servers based on Fedora 9 i even skipped F9
and upgraded directly from F8 to F10 on desktop machines
so *no* you do not need years of technical skills, learning by doing works
