[Bug 23660] Re: [network-admin] 'Enable this connection' option in network settings is redundant

[Pascal De Vuyst]

Furthermore the main interface (eth0 on my computer) can't be deconfigured by removing the tick in "Enable this connection".
Trying to do this results in the following lines being added to /etc/network/interfaces:
iface eth0 inet dhcp
auto eth0
After restarting network-admin the interface eth0 is activated and 
configured as dhcp.

Since this result is unexpected this proves that the "Enable this
connection" checkbox is a bad idea.
