I guess the following changes do kind of a job:
etc/udev/rules.d/69-bootif.rules (inside the installer's initrd)
ACTION=="add", SUBSYSTEM=="net", IMPORT{program}="bootif $attr{address}"
lib/udev/bootif (inside the installer's initrd)
#!/bin/sh
bootif="$(< /proc/cmdline sed 's/.*[[:space:]]BOOTIF=\([-0-9A-Fa-f]\+\).*/\1/' | tr '[A-F-]' '[a-f:]')"
if [ "01:$1" = "$bootif" ]; then
echo INTERFACE_NAME=eth0
fi
Unfortunately, this seems to go a little too far. My test system comes
up with the second interface being the bootif, so it's eth1 without
these additions. With my additions, the following numbering happens:
MAC Address without additions with additions
A eth0 eth4
B eth1 eth0
C eth2 eth3
D eth3 eth5
The /etc/udev/rules.d/70-persistent-net.rules that is being generated
has the first interface found twice:
ATTR{address} NAME with additions
C eth2
C eth3
B eth0
A eth4
D eth5
I guess there may be a race going on. Is there any possibility to have
bootif honored without generating a broken 70-persistent-net.rules and
with still having the interfaces numbered consecutively?
Greetings
Marc
