Description of Problem:
The /sbin/ifup script which activates and configures network devices in RedHat
Linux is forcing the 'scope' property of addresses added to devices to 'host'
for the loopback device and to default (global) for all other devices.

It would be useful to be able to customize the scope field, since this allow a
finer selection of source addresses of network connection from the machine
(among others).

Version-Release number of selected component (if applicable):
ALL
