Re: [coLinux-users] getting rid of old ethernet devices

[Andrew R. <and...@gm...>]

Ah, thanks!

A few questions as I try to understand this.  Isn't the purpose of udev to
keep the devices the *same*?  It seems pretty bizarre to increase devices on
every boot -- that's a lot of new devices.  Ubuntu (which I'm using) doesn't
seem to add devices on boot, only on actually new tap devices (maybe this is
what you mean?).

I'm also a bit confused by the workaround of adding a new mac address per
device.  I thought you would want to force each new tap device to use the
same mac address, to trick linux into thinking they're new devices?
