I disabled network. For all runlevels. Rebooted. Did not see any
messages about starting loopback.
Opened a terminal window and did a ifconfig. There was lo with 127.0.0.1
(along with ::1). pinged 127.0.0.1. Does not look good. looked at dmesg,
grepping for NET. Families 16,2,1,17,10, and 31 registered.
So looks like I am stuck with IPv4 no matter what. Unless there is some
magic glue in rc.sysinit.
