returning the controls back to the sys admin...
network-manager doesn't work or manage... it's unnecessary... it's harder to figure out the "convenience" tool
than it is to learn the key flat files and edit them using the vi editor in a shell.
got tired of fighting DNS and network issues... network-manager failed on my home network, and on the road in hotels...
life is better when developers follow the UNIX/Linux philosophy!
people can learn... the microsoft mentality infected redhat and resulted in bloated,
complex systemd related "features" that complicate basic real world sys admin tasks...
setting up users and networks used to be easy... just a few files to edit...
well, I'm going back to the basics... going to make Linux Mint MATE and SuSE with MATE
return there and then likely setup Anti-X (antics) because it's based in MUD... Mint, Ubuntu and Debian...
a GREAT DISTRIBUTION base with lots of excellent packages and a thriving user community!!!
let's ditch systemd, return to inetd and figure out how to provide GUI tools for newcomers that educate
on what files they are editing... they don't need to necessarily learn vi, but they should know about the
files and have a GUI tool that guides the editing of the system flat files with safety checks, rather
than writing microsoft-like bloatware that could lead to future security issues...
well, here's what I "hacked" to get my system back...
