Regressions Of GNU\Linux

Change is not always for the better.

tab completion on dhclient

In Debian 8 (Devuan Jessie), you can type # dhclient eth, then hit tab to get the completion for eth1,eth2,eth3, etc... This no longer works in Debian 9 (Devuan Ascii). It's necessary to write out the full eth#.

Udev requires reboots after Ubuntu 14

When I started using Linux distributions one of the things I noticed was how well updates were handled, compared to proprietary software. No forced reboots, no update screens that leave the user waiting. You can use your computer while it's updating. This changed with udev requiring a reboot in Debian 8 or 9 occasionally.

Apt instead of Apt-get

This is a tentative, based on whether they remove support for apt-get. If that is the end goal, then this will be a valid regression, until then, they live side by side.

ifconfig replaced with ip

ifconfig, is simpler to use, and easier to view for basic nic information. ip is unnecessary complexity for most use cases.

/etc/resolv.conf depreciated

All you should need for DNS is a pointer to a DNS server. Put that in /etc/resolv.conf. The simplicity of that is a threat to more complicated OS, therefore there will be an effort to complicate it.
