WANBOOT/Jet/Solaris 10 issues?

Question

I've tried booting via wanboot pure and cdrom method with the same results. I am using JET with a Solaris 10 01/06 and 06/06 images and have the same problems. Anyone seen this or can comment?
Below is the output from the install.

Answer 1

Check your boot image
/export/install/media/10u5/Solaris_10/Tools/Boot/etc/inet
for the following links
lrwxrwxrwx 1 root root 32 Sep 2 15:00 netmasks -> ../../tmp/root/etc/inet/netmasks
lrwxrwxrwx 1 root root 31 Sep 2 15:00 ipnodes -> ../../tmp/root/etc/inet/ipnodes
lrwxrwxrwx 1 root root 29 Sep 2 15:00 hosts -> ../../tmp/root/etc/inet/hosts
I have seen a similar problem today where links were replaced by files causing an identical error
