SUMMARY: ifconfig not holding after reboot

Thanks to all who offered assistance.  Darren Dunham pointed me to my 
problem which prevented my virtual interfaces from coming up properly:

Not that I don't believe you, but could I see the output for 

wc -l /etc/hostname.*

If they don't all say '1', then that's your problem.


Indeed, when I had edited the /etc/hostname.eri* files, I inadvertantly 
added a second blank line.  Once I removed the blank line, I rebooted 
and my interfaces are now properly automatically configured.

Most others suggested I be sure I didn't muck up my /etc/hosts or 
/etc/hostname* files as specified below by Allan West:

We use many virtual interfaces on our machines, and make a file for each 
one named:
	/etc/hostname.INTERFACE
eg.
	/etc/hostname.hme0
	/etc/hostname.eri0
	/etc/hostname.eri0:1

Each file has the hostname for the interface, eg.
	machine1.domain.org
	machine2.domain.org
	web.domain.org

and those names match entries in /etc/inet/hosts to get their IP address. 
Do you have each hostname in the /etc/inet/hosts file for lookup?
