Continuing my Bookmarks serie, here is how to tell NetworkManager to not manage an interface, thank you very much:
~# sudo cat >> /etc/NetworkManager/NetworkManager.conf << EOF
plugins+=keyfile
[keyfile]
unmanaged-devices=interface-name:IFNAME
EOF
Where IFNAME
is the interface name. For example:
unmanaged-devices=interface-name:eth0
Will prevent NetworkManager to manage eth0 …
