I think the more you dig the more you find you could learn
True, but it’s really frustrating to spend time to learn something that’s maybe going to be useless ? Just look at networking in linux distros between networkd, NetworkManager, netplan, nmtui, nmcli, networkctl, ifupdown… all working in different locations and all having their own way of doing things… This is is fucked up :/
Imagine learning docker’s all subtilities and next year it’s deprecated in favor of another technology with his own flavors and commands… :/
