Since my initial response to this message I have done some more
research on udev, and I now agree with you 100%. In my initial
response I said something about how the copies in /etc/udev/rules.d
were intended to be "user editable". There is an element of truth
to that. I'm thinking, for example, of /etc/udev/rules.d/70-persistent-net.rules,
on the i386 architecture, which is generated by /lib/udev/write_net_rules.
This file assigns network interface names (eth0, eth1, etc.) based
on the MAC address and is user-editable so that the user can decide
which MAC address to assign to which interface.
However, in the case of 65-sysconfig-hardware-net.rules and
85-sysconfig-hardware.rules, these are not generated files and
contain nothing that would ordinarily be considered user-customizable.
I can see no reason for them to be in both /lib/udev/rules.d and
/etc/udev/rules.d. There seems to be conflicting evidence here.
According to the web page
http://packages.debian.org/squeeze/s390/sysconfig-hardware/filelist
the two rules files exist only in /lib/udev/rules.d. But according
to /var/lib/dpkg/info/sysconfig-hardware.list on my actual installed
system, they exist in both places. I have erased the copies in
/etc/udev/rules.d on my system. Perhaps this will save me some trouble
on the next upgrade.
