#Added by Mason. The files this creates store all the IP's an interface
#has used. Mason uses these to figure out the smallest network that will
#accomodate all these IP's.
#This short section of code (without the first "#"):
#
# [ -f /var/lib/mason/saveips ] && . /var/lib/mason/saveips #Added by Mason
#
#should be appended to:
# - /etc/rc.d/rc.local (or some file that gets run at boot time)
# - any script that's run _after_ a new IP address is acquired, such as:
# - /etc/ppp/ip-up or /etc/ppp/ip-up.local
# - /etc/dhclient-script
# - /etc/sysconfig/network-scripts/dhcpcd-eth*
# - /etc/pcmcia/network (in the start_fn function)
#FIXME - add to Makefile and install scripts...
