If you want me to post everything, let me know... for now i'm cutting a
lot out

SIOCADDRT: File exists
okay, i don't have a networking/default directory (I have a
networking/profiles/default, but it's empty)
it's pulling NETMASK=255.255.0.0, but when I do type ifconfig it shows
netmask 255.255.255.255, and in my ifcfg-ctc0 i have NETMASK=255.255.255.128
It's not doing MTU=1500 either
SIOCADDRT: File exists? That happens if I "route add" something that's
already there

SIOCADDRT: File exists
+ /etc/sysconfig/network-scripts/ifup-post ifcfg-ctc0
Again, this value for NETMASK and no MTU... where is it coming up with this?
I had mentioned opts wasn't getting set, earlier:
echo "ifconfig ${DEVICE} ${IPADDR} ${opts} pointopoint
${REMIP}">/tmp/ctc.log
in the script yielded
ifconfig ctc0 172.16.18.130 pointopoint 172.16.18.129
I'm all ears,
