Comment 10 for bug 1704376

I confirmed that the contents of file /etc/network/interfaces.d/eth0.cfg

pre-up [ -z `cat /proc/net/bonding/* | grep Slave | grep eth0` ] && true

is manually set by preseed.

but still, 2.2 need to handle this or ignore this as 2.1 did.

Please give me your opinion.

Thanks.
