Thank you Jens for the reply.  Now I see what's going on.

It is not udhcpc, and not the udhcpc script either.  It is busybox's
`ip' utility.

# busybox ip -4 add 192.168.77.10/32 dev dummy0
ip: invalid argument '192.168.77.10/32' to 'ip'
# busybox ip -4 add 192.168.77.10/31 dev dummy0
# _

And this is exactly what's used in the udeb script:

        bound|renew)
                ip -4 addr add "$ip/$subnet" dev "$interface"

So I'm retitling the bugreport accordingly, and will
try to fix it now, when it is clear where the problem
is, exactly.

Thank you very much guys for the help!
