Re: problem with networking cropped up after upgrading to sid
/dev/tap0 is the node for accessing the kernel ethertap driver. It is
used by some programs such as diald. If you have something like that
installed, it will probably autoload the kernel module ethertap.o on
bootup. You can probably find out when it gets loaded by looking at
/var/log/syslog or 'dmesg | less'. Then just remove the program that
causes ethertap to be loaded, and see whether your routing problem
goes away.
Very sketchy, but I hope it helps you anyway.
