Package: base-installer
Version: 1.154
Tags: patch

Dear Maintainer,

I am trying to install Debian jessie on an arm device (Zyxel NSA325).
The device isn't yet officially supported by d-i and I had to make some
changes to d-i to run it on the device. I am willing to share my work as
soon as possible.

During the installation I get a message that the installer was unable to
find appropriate kernel package for the device.

    No installable kernel was found in the defined APT sources. [...]

I have traced the the message and it comes from pick_kernel() in
/usr/lib//base-installer/library.sh. In /var/log/syslog I find a message

    Jan  1 00:52:06 base-installer: info: could not determine kernel flavour

repeated several times and followed by

    Jan  1 00:52:06 base-installer: info: Found kernels ''

A very brief investigation suggests that that the problems comes from
the references to unassigned $FLAVOUR variable. I may only suspect that
the code containing $FLAVOUR has been moved from some file without
moving actual assignment (like the one in
debian/bootstrap-base.postinst)

The attached patch renames occurrences of $FLAVOUR in library.sh to
$KERNEL_FLAVOUR. A quick in vitro test in a d-i shell

--8<---------------cut here---------------start------------->8---
. /usr/lib/base-installer/kernel.sh
. /usr/lib/base-installer/library.sh;
kernel_update_list
cat /tmp/available_kernels.txt
--8<---------------cut here---------------end--------------->8---

returns expected results:

--8<---------------cut here---------------start------------->8---
linux-image-kirkwood
linux-image-3.16.0-4-kirkwood
--8<---------------cut here---------------end--------------->8---

and the installer presents a nice list of available containing the two
above and a "none" option.
