Bug#883664: DEVICE= in initramfs.conf is ignored

[Ivan Kozik <ivan@ludios.org>]

Package: initramfs-tools
Version: 0.130

Dear Maintainer,

I was using initramfs-tools with dropbear-initramfs on stretch and
discovered that configure_networking would always set up DHCP on the
wrong network interface, even if DEVICE= was set in
/etc/initramfs-tools/initramfs.conf.  (It would try both, succeed on
the faster-responding DHCP server for the interface I didn't want,
then give up on the other.)

I tracked this down to a lack of `export DEVICE=` in
/usr/share/initramfs-tools/init, causing DEVICE to be unset in
configure_networking.

I have attached a patch.  I tested it on stretch and confirmed that a
DEVICE= in /etc/initramfs-tools/initramfs.conf set up DHCP on the
corresponding interface.

Thanks,

Ivan

Subject: [PATCH] init: export DEVICE so that when configured, it is actually
 set in configure_networking
