build a CD from varous repositories

[Geronimo Ma. Hernandez]

Hello,

I started with the toolchain and the "mirror-sync" script from alioth.
All parts played together and I got my first self-build image.

Now I would like to add packages from other repositories to the CD - so I have
to mirror them too.

The run of the mirror-sync wasted most of my diskspace with packages, that
never would go to CD - and I don't know, whether all repositories fit on a
single partition.

Is there a (documented?) way to create partial mirrors from various
repositories, so the building of the CD can succeed?

I think of a way like apt-get works, based on packagelist and sources.list -
but without caring about the installed packages on the host.

Any hint is appreciated.
Geronimo

Try 'debmirror' (or one of the similar packages).

Hello and thank you for your support.

> Try 'debmirror' (or one of the similar packages).

I already used your script (mirror-sync) which wrappes debmirror.
The point is, that (from my understanding) debmirror only works with
blacklists (--exclude).
... and so far, I don't know, what I should exclude.

I wrote a tasklist which after "make packagelists ..." results in a file
called "list".

I would like to use that file to create my local partial mirror - cause I'm
only interested in that packages plus their dependencies - no matter how many
CD-images I'll have to create.
I tried to use apt-get with --download-only, but it knows nothing about udebs.

Imagine that I like to add virtualbox from
http://download.virtualbox.org/virtualbox/debian on my CD. I don't know, how
many files the repository of virtualbox.org contains - and I don't like to
care about. I only know, that I want to add virtualbox with all its
dependencies. My sources.list includes all repositories necessary - so an
apt-get install works.
virtualbox is only one package from an non-debian repository. I have various
packages from several other repositories.

Can the apt-get environment be used to create a local mirror that is usable to
build a CD(-set)? Or can I combine various tools to solve that?
I don't fear about writing scripts - the point is, I don't know, how I could
solve the problem.

kind regards
Geronimo

That's why I added the second link. See my last post there. It has some
examples of what could be excluded.

That's very extreme... I don't think you could still call that a useful
mirror. Debmirror is not the tool for that. Don't know of any
alternatives.

Can't help you there. Sorry.

you could try simple-cdd:

  http://wiki.debian.org/Simple-CDD

it generates a partial mirror based on what packages you're interested in, and
uses debian-cd to generate a CD image based with those packages.

it has some support for multiple repositories, and there are some tricks for
adding custom packages as well.

live well,

Hello vagrant,

thank you very much for your attention!

I have 2 virtualboxes (sid and lenny), where I perform the excercises.
Simple-CCD doesn't work for sid, nor for lenny. And I have completely
different errors that are documented.

I'm not that used to shellscripting, so I startet with a little perlscript,
that should build my partial mirror. That script already is able to fetch and
scan Release- and Package-files and process a local packagelist.  I started
with the list, generated from debian-cd by "make packagelists ...", but
without trying to solve dependencies yet, I have packages, that could not be
found at all - neither scanning for package-name, nor scanning
for 'provides'.

I think I miss a lot of understanding from package-organisation, so it seems
not to be a solveable problem for me, create a custom cd.

kind regards
Geronimo

Hello,

I did some additional investigations, but did not understand the result. Is
any you cracks willing to take a look at my script and shine me a light on
what I'm missing? I would appreciate it a lot.

Currently my (perl-)script only fetches Release-files and Package lists, no
deb-files yet. Also it does not support any cmdline options yet.
It creates a 'tmp' directory in the current directory, using that
tmp-directory as target for the downloads.

The repositories are taken from /etc/apt/sources.list
and /etc/apt/sources.list.d/*
Simple support exists for /etc/apt/preferences.

It needs a packagelist as parameter. That packagelist should be in the current
directory.

I did the testing by: "resolveList pkg.list 2> missing > 2download"

The file 2download looks fine to me, but I don't understand the content of
missing.

kind regards
Geronimo
