We use aptly to manage our debian repositories.
TODO
Assuming we have the following local mirrors,
$ aptly mirror list
List of mirrors:
* [debian-testing-contrib]: http://ftp.debian.org/debian/ testing [udeb]
* [debian-testing-main]: http://ftp.debian.org/debian/ testing [udeb]
* [debian-testing-non-free]: http://ftp.debian.org/debian/ testing [udeb]
here is how you can create the snapshots from the local mirrors.
$ aptly snapshot create debian-testing-main1 from mirror debian-testing-main
$ aptly snapshot create debian-testing-contrib1 from mirror debian-testing-contrib
$ aptly snapshot create debian-testing-non-free1 from mirror debian-testing-non-free
The local repos are going to contain our own packages and the modified debian
packages. Following commands create the local repos pardus-devel-main,
pardus-devel-contrib, pardus-devel-contrib.
$ aptly repo create -component="main" -distribution="pardus-devel" -comment="Pardus devel main component" pardus-devel-main
$ aptly repo create -component="contrib" -distribution="pardus-devel" -comment="Pardus devel contrib component" pardus-devel-contrib
$ aptly repo create -component="non-free" -distribution="pardus-devel" -comment="Pardus devel non-free component" pardus-devel-non-free
In the following command, aptly recursively goes through all the folders under
the directory path/to/packages and adds the binary and source packages it
finds to the local repo pardus-devel-main.
$ aptly repo add -force-replace pardus-devel-main path/to/packages/
You can also add a single package to any local repo by explicitly giving the *.deb file path.
First create snapshots of the local repos. Note that if a local repo is empty, you can't take its snapshot.
$ aptly snapshot create pardus-devel-main1 from repo pardus-devel-main
And then merge the snapshots as follows.
$ aptly snapshot merge merged-pardus-devel-main1 debian-testing-main1 pardus-devel-main1
NOTE: The order of the source snapshots matters in the command line. Aptly
merges the snapshots from left to right. It favors the packages in the
rightmost source snapshot out of packages with the same (name, architecture)
pair. Also see -latest and -no-remove flags in aptly.
Publish the snapshots as follows.
$ aptly publish snapshot -architectures="i386,source,amd64" -gpg-key="B8B5F2D5" -component=main,contrib,non-free -distribution=pardus-devel merged-pardus-devel-main1 debian-testing-contrib1 debian-testing-non-free1 pardus
Because pardus-devel-contrib and pardus-devel-non-free local repos are
empty, we can not take their snapshots. When we add packages to these local
repos, We merge their snapshots with their corresponding debian testing
snapshots and publish them. For the time being, we publish
debian-testing-contrib1 and debian-testing-non-free1 snapshots, instead of
merged-pardus-devel-contrib1 and merged-pardus-devel-non-free1.
Add new packages to the local repo.
$ aptly repo add -force-replace pardus-devel-main path/to/package/
Take a new snapshot of the local repo.
$ aptly snapshot create pardus-devel-main2 from repo pardus-devel-main
Merge snapshots
$ aptly snapshot merge merged-pardus-devel-main2 debian-testing-main1 pardus-devel-main2
Following command switches from merged-pardus-devel-main1 snapshot to
merged-pardus-devel-main2 snapshot in the published snapshot pardus/pardus-devel.
$ aptly publish switch -component=main,contrib,non-free pardus-devel pardus merged-pardus-devel-main2 debian-testing-contrib1 debian-testing-non-free1
When we build debian-installer package, we also get a
debian-installer-images_20160630pardus1_amd64.tar.gz file. In order to build
an ISO file, we should extract this into
/srv/mirrors/public/pardus/dists/pardus-devel/main.
tar -xf /tmp/packages/debian-installer/debian-installer-images_20160630pardus2_amd64.tar.gz -C /srv/mirrors/public/pardus/dists/pardus-devel/main
TODO: I don't know if this is the proper way of doing this!
