Hello fine readers,
Chances are you're scouring the googles much like I was all morning trying to figure out how to get
update-initramfs to pull in the
70-persistent-net.rules udev rule.
I quickly found that
NEED_PERSISTENT_NET=yes needed to be set, but it wasn't immediately obvious where that needed to be set as
update-initramfs ignores environment variables. Well, I finally tracked down a reference to where you can set that variable.
In the case that link dies, or that line is removed here is the necessary information:
Usually network interfaces are renamed after the root file system has been mounted, so if the root file system is mounted over the network then the 70-persistent-net.rules file must be copied to the initramfs. In most cases this is done automatically, but some setups may require explicitly setting
"export NEED\_PERSISTENT_NET=yes" in a file in /etc/initramfs-tools/conf.d/. If 70-persistent-net.rules is copied to the initramfs then it must be updated every time a new interface is added.
and added it to my deployment script:
echo "export NEED_PERSISTENT_NET=yes" > /mnt/etc/initramfs-tools/conf.d/persistent_net_setup
which triggered the copying of
70-persistent-net.rules the next time I ran
Hopefully this helps you out!
