It is very, _very_ important. Those 16 secotors is where bsdlabel(8)
store its metadata. If you put 0 there, be ready to lose your
partitions.

Swap skips first 16 sectors, so it won't touch it. UFS skips first 16
sectors, so you are safe here as well, but those are evil hacks.
If you configure something else on first partition which starts at
offset 0 (eg. encrypted partition) you are in big troubles.
