Package: ifupdown
Version: 0.6.8+nmu1
Severity: wishlist
Tags: patch
The attached patch (based on 0.7~alpha3) adds support for a "privext" option
for IPv6 static, manual & v4tunnel, taking an integer parameter exactly as
for the net.ipv6.conf.$INTERFACE.use_privaddr sysctl.
I've tested only manual (I'm using radvd). I find that the 'inet6'
configuration for a given interface must be before the corresponding 'inet'
configuration (if present) else the "privext" option won't take effect until
the interface is *next* brought up (based on brief testing by taking the
interface down then bringing it up again a second or so later). Not sure
where/how to document this...
