custom repository howto (The aurex way)
=======================================
packages: reprepro inoticoming gnupg apache2

gpg keys
========
We need to generate signing key as root, so, the recommended way is:
	sudo su -
	gpg --gen-key
 -> option (2) DSA y Elgamal
 -> size: 1024
 -> option 0 = (no caducity)
 -> Name: aurex linux repository
 -> email: aurex.linux@gmail.com
 -> Comment: <empty>
 -> pass phrase: <empty>

execute:
	gpg --list-keys

an then look for a line similar to:
	...
	pub  1024D/3D3CBB05 2011-09-02

(the part after 1024D/ is the required reprepro configuration key)

The public key should be exported (and published) in an ASCII armored file.
To export the key, run:

gpg --export --armor 3D3CBB05 > repo-key.asc

reprepro
========
create repo dirs, in our example:
	mkdir -p /srv/repo/aurex/conf /srv/repo/aurex/incoming /srv/repo/aurex/incomingtmp
To easy allow local uploads, a quick an dirty trick is to create a system group ('uploaders') and change ownership and permissions in the incoming dir. In our example:
	addgroup --system uploaders
	chgrp uploaders /srv/repo/aurex/incoming
	chmod 775 /srv/repo/aurex/incoming

Generate the reprepro configuration files:
(see conf directory in git ...)

We need to write an update rule for every "url-suite-arch" combination, because we generate 'per arch' lists. In our example, we are going to update from two different ppa's, so we edit conf/updates in the form:

cowbuilder
==========
create chroots:
	sudo cowbuilder --create --distribution precise --components "main universe" --basepath /var/cache/pbuilder/precise-amd64.cow
	sudo cowbuilder --create --distribution precise --components "main universe" --architecture i386 --basepath /var/cache/pbuilder/precise-i386.cow

update:
sudo cowbuilder --update --basepath /var/cache/pbuilder/precise-i386.cow
sudo cowbuilder --update --basepath /var/cache/pbuilder/precise-amd64.cow

compile:

sudo DIST=lucid ARCH=i386 cowbuilder --debbuildopts "-b" --build ../hello_2.4-3.dsc --basepath /var/cache/pbuilder/lucid-i386.cow

NOTE: --debbuildopts:
	"-b" binary only
	"-S" source only (uses 'source' as arch, so geerates generates: $p_$v_source.changes file)
results in:
/var/cache/pbuilder/result/

/etc/pbuilderrc
---------------
# this is your configuration file for pbuilder.
# the file in /usr/share/pbuilder/pbuilderrc is the default template.
# /etc/pbuilderrc is the one meant for overwriting defaults in
# the default template
#
# read pbuilderrc.5 document for notes on specific options.
