Do not download on metered connections in checkupdates
I have a systemd job running to regularly download packages in the background. In order to not download over metered connections I use the following line for ExecStart
ExecStart=/usr/bin/sh -c 'nmcli -t -f GENERAL.DEVICE,GENERAL.METERED dev show | grep -q :no && checkupdates -d
Would a check for metered connections directly in checkupdates be interesting for the general public?
