ah, interesting. this also explains why I don't see my hostname at home
because (for historical reasons) I have a dummy interface too
which doen't hsa the broadcast flag set either:

# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Bcast:0.0.0.0 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:3924 Metric:1
RX packets:428560 errors:1719 dropped:0 overruns:0
TX packets:0 errors:0 dropped:0 overruns:428560

dummy0 Link encap:10Mbps Ethernet HWaddr 00:00:00:00:00:00
inet addr:10.2.170.191 Bcast:10.2.170.255 Mask:255.255.255.0
UP RUNNING NOARP MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0
TX packets:0 errors:0 dropped:0 overruns:51127

eth0 Link encap:10Mbps Ethernet HWaddr 02:07:01:16:ED:D4
inet addr:10.2.170.191 Bcast:10.2.170.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0
TX packets:0 errors:0 dropped:0 overruns:0
Interrupt:9 Base address:0x300 DMA chan:3


after `ifconfig dummy0 down' I get at least one chooser entry for hostname.


but how can I get an entry for localhost again with 2.1.x ?
I tried `ifconfig lo broadcast 127.255.255.255' but this didn't
set the BROADCAST flag.

is this a design decission in 2.1/2.2 that broadcasts are not possible
at all (and not only off by default) for lo and dummy devices
or is this just a bug ?
