I've been doing this since RH 7.3. I'm an old fart and I don't do change well. There are 49 SystemD man pages. Each one is more esoteric than the Talmud. Seriously. "Chkconfig" made perfect sense to me. I just need one example to figure it all out. If I want squid to start in L-5 but not L-3. What do I do? Thanks
