That’s only for the sid kernels, not for
sarge and etch which
are positively
prehistoric now.

You can
also, at this point, speed things up and make them
simpler by getting a pre-made filesystem image
(ext2 though)
or tarball; I’ll show the
latter. This has the benefit of not
assuming
a Debian system as PC host; it could even work with
BSD (though most BSD only know ext2fs not
ext4fs which you
really want to use on Linux
these days) and possibly (didn’t
test, I
don’t have it) MacOS X.
4a) Download it to where there is enough space
(on the PC):
$ wget
http://zigo.mirbsd.org:8080/t/2015-Jan/Ara2015A.tar.gz
4b) Verify the hash:
$ sha256sum
Ara2015A.tar.gz
This
should output:
caa27e8dd05950d92e34c0d5e6a2b753f96fd8a62bb257b13f3f9af85d1789c2
Ara2015A.tar.gz
There’s also http://zigo.mirbsd.org:8080/t/2015-Jan/README.txt
which I PGP-signed and contains the same
hash.
4c) Extract the
tarball while preserving permissions:
$ cd /mnt
$ sudo
tar xzpf /path/to/Ara2015A.tar.gz
4d) Copy the kernel and initrd out:
$ cp
/mnt/boot/initrd.img-3.16.0-4-m68k /tmp/
$ gzip -d </mnt/boot/vmlinuz-3.16.0-4-m68k
>/tmp/vmlinux-3.16.0-4-m68k
4e) Adjust some configuration files:
$ sudoedit
/mnt/etc/network/interfaces
(default
network config: eth0 is 192.168.10.6, no DHCP)
$ sudoedit /mnt/etc/hostname
/mnt/etc/hosts
(set the hostname you
wish the machine to have)
If you want to use DHCP, remove the
line
iface eth0 inet static
and everything after it, and add a
line
iface eth0 inet dhcp
in its place. It’s installed in this
image.
Otherwise /mnt/etc/resolv.conf
may need to be edited, it uses
some
well-known public “spy agency” DNS resolver by
default.
4f) Create some
entropy on the target filesystem:
$ sudo dd if=/dev/urandom bs=512 count=1
of=/mnt/var/lib/urandom/random-seed
$
sudo chown 0:0 /mnt/var/lib/urandom/random-seed
$ sudo chmod 640
/mnt/var/lib/urandom/random-seed
>5) Umount the root filesystem from /mnt and
mount the primary
> AmigaOS
partition to /mnt instead.
Copy
amiboot-5.6 into a new directory on the AmigaOS system.
6) Place the kernel
(decompressed) and initrd into that new
directory as well:
$ sudo cp /tmp/vmlinux-3.16.0-4-m68k
/mnt/path/to/new/dir/
$ sudo cp
/tmp/initrd.img-3.16.0-4-m68k /mnt/path/to/new/dir/

root=/dev/sda2 fb=false
console=ttyS0,9600n8 devtmpfs.mount=1"
Of course, adjust the
root/fb/console parameters, I just took them
from Adrian’s example. Do *not* set
init=/bin/bash (as this system
is already
completely configured), but *do* set devtmpfs.mount=1.

Double-click the script you created in 7) and wait for

10) Log in as root with the
password "root" (not including the quotes).
Start GNU screen, so you
can continue to work in another
terminal (press ^Ac to create one, then ^A<space> to
cycle
through them) when one is
running a time-consuming job:
# screen
Set a new password:
# passwd root
11) Install a few more packages. Now is a good
time to add an
SSH server, and
possibly your favourite editor (the image
has ed, jupp, and mcedit by default; you may wish to
add
nano or vim-tiny if you like them,
or joe-jupp for jmacs,
which has
Emacs-like UI, or mg, another small Emacs-ish
editor). These commands are dependent on
each other, but
while they’re
running, you can use a second GNU screen tab
to further explore the system, e.g. with
"mc".
Update the package lists (this will take several
minutes!):
# dselect update
# or: apt-get update
Now run this command, it needs to be run
only once after
the base tarball is
extracted, to finish setting up the
packages I specifically marked as needing that; by this
point, the system should have some
entropy (both from the
urandom/random-seed file you created earlier, and from
your activity (keyboard input, network
I/O) you already
did and, more
importantly, the hostname should be right
by now! It takes a short time only.
# dpkg -a --configure
Now you can install extra packages:
#
apt-get install openssh-server # and maybe others
If you
did choose another editor, edit /root/.profile and
add a line (near the bottom) that says,
for example for mg:
#
echo export EDITOR=mg VISUAL=mg >>/root/.profile
If you wish to make this
the system-wide default, use:
# echo export EDITOR=mg VISUAL=mg
>/etc/profile.d/editor.sh
Now is a good time to
start the, rather lengthy unfortunately,
process to get the system up-to-date. Make sure you have
all
packages you’ll need for the
next few hours installed, so you
can
continue to work in another screen tab (e.g. run
adduser),
then run…
# apt-get --purge upgrade
--with-new-pkgs
… which is safe to
do at this point as you "dselect update"d
earlier.
Review the list of actions
(this one should be safe, but one
never knows) that is shown after a minute or two, then
hit
"y" and Enter. If it
does not work, drop the “--with-new-pkgs”.
After that, or – if
you’re feeling adventurous and know Debian
“unstable” system administration
fairly well – instead of it,
you can
run…
# apt-get --purge
dist-upgrade
… instead, but this may
not work, or want to remove important
(to you) packages.
Every time a new kernel version is installed (i.e. one of
the
linux-image-* packages is updated)
or a new initrd is generated
(you’ll
see that in the output), you must copy them out to the
AmigaOS partition and possibly adjust the
start script (it’s
also a good idea
to keep a backup or two around). You may wish
to add the AmigaOS partition to
/etc/fstab to make this easier.
