 Uhm. I guess it's kind of a false alarm, not regression from 8.1 :)
 
 The problem is this:
 
 # getent hosts create
 85.128.167.158    create.pl
 
 so ifconfig sees that gif5 interface exists and so decides I wanted to
 change the IP and resolves "create", gets the IP, and basically executes:
 
 # ifconfig gif3 85.128.167.158
 ifconfig: ioctl (SIOCAIFADDR): Destination address required
 
 IMHO it still should not clear the old address in this case.
