Re: SL6 to SL7 transition guides?

For systemd, I learned a lot from this series in fedora Magazine:

My cheat sheet is here - scroll down past the installer bits to the meat
on setting up NIS, NFS, google-chrome, disabling junk services. Only el6 and el7
things shown, for el4 and el5, you will have to go back through the wiki 
history.

I don't think I could do Fedora on servers :P

I'm moving a lot across to EL7 - and with it, a few systems are giving
me grief with custom systemd stuff being required and a few of the old
ways not quite working like they used to.

Thankfully, I can avoid the abomination that is Gnome 3 and run
everything headless - no GUI anywhere near EL7. I'm ok with that.

Fedora however, I agree is ok for the desktop - in fact, better than EL7.

Yup. One thing you'll learn really quickly is that RH abandoned TONS of
packages to EPEL - meaning they don't have to actually support them.

A lot of things that used to be in the core repos are now not.

If you're doing desktop stuff, I don't think EL7 has it anymore - may as
well use Fedora. I use Fedora + KDE5 on my laptop and its about as good
as gnome was before the great dumbing down that made Gnome 3.

And yeah, I get told off in the official channels all the time for this,
but I still disable selinux on just about everything.
