rsync: numericids option is always enabled

This

L890 in /usr/share/backupninja/rsync: "if [ ! -z "$numericids" ]; then"

This checks if the field is a zero-length string. So if it's set to "0", then this condition is true.

Meanwhile on L179 and L220: "getconf numericids 0"

So it defaults to "0", which causes the aforementioned condition to be true.

The fix is to switch the two getconfs to "getconf numericids".
