# 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

# Yes, /lib/dhcpcd is correct, even on x86_64.
