Package: udev
Version: 0.105-3
Severity: grave
Justification: renders package unusable
Recent udev and/or kernel versions appear to have introduced a "feature"
that is problematic.
/lib/udev/write_net_rules -- NOT a conffile -- is saving persistent
network information by default. This means that the system breaks when:
* An Ethernet card is swapped for a different hardware
it may now become eth4 or some such instead of eth0
* A hard drive is moved to a new machine
Even if the Debian kernel can autodetect the hardware appropriately,
suddently the network breaks because again eth0 is taken to
be a MAC address that doesn't exist
* A tool such as systemimager is used to manage the installation
of multiple Debian machines based on a common image
I can understand why the feature exists, BUT:
* Should it be on by default? I think not. If software probing
stability is so poor that this is needed by default, the problem
lies elsewhere.
* This is not documented anywhere obvious. It should at least
be documented in the interfaces manpage, and hopefully elsewhere
(somewhere more obvious than buried in udev)
I think that this ought to be fixed for etch; otherwise, we'll have some
nasty surprises.

Looks like you missed the last couple of years of discussions about this.
Short summary: persistent naming for network interfaces is needed and
useful and will not be changed any time soon.

Then please open a bug against an obvious package.
