# At this point, it should be safe to assume that /var will be mounted by the
# time dhcpcd is called, as all non-root local filesystems are mounted from
# /etc/rc.d/rc.S, and /var should not be on a network filesystem.  As such,
# we'll use the FHS layout instead of putting things in /etc/dhcpc

# The n/NetworkManager package now uses an internal dhcp client due to
# compatability issues.
# It's recommended to set this to 'yes'.
