# Mirrors SMF's system/device/local method (lib/svc/method/devices-local).
# devfsadm configures hardware; soconfig loads /etc/sock2path.d into kernel
# sockfs so socket(AF_INET, ...) and socket(AF_INET6, ...) actually return
# a valid fd. Without soconfig, every socket() of those families fails
# EAFNOSUPPORT and ifconfig cannot configure any interface — including lo0.
