nmconnection vs link vs ifcfg files
Wtf is the difference between .nmconnection .link and ifcfg-* files.
/etc/NetworkManager/system-connections/*.nmconnection = network manager configuration keyfiles https://developer.gnome.org/NetworkManager/stable/nm-settings-keyfile.html
/etc/systemd/network/*.link = systemd network configuration files using the ‘new’ syntax https://www.freedesktop.org/software/systemd/man/systemd.link.html
/etc/sysconfig/network-scripts/ifcfg-* = init scripts still used for legacy, it is processed by systemd anyways https://developer.gnome.org/NetworkManager/stable/nm-settings-ifcfg-rh.html
my systemd btw:
