Mirrors policy

Needed:

• expiry policy; to know what is actively supported and what is not (likely to move to an archive section)
• archive section; so that a mirror may move archived stuff on cheaper storage systems
• announcement/discussion mailing-list
• release plan (see http://mageia.org/en/calendar/ that already hosts Mageia release schedule).
• mirroring tools (rsync, mirrorbrain, mirrormanager?)
• better organization of this doc

Available media

First, a table summary:

media	required for mirror?	enabled by default?
		release	updates	updates_testing	backports	backports_testing
core	Yes	Yes	Yes	No	No	No
nonfree	Yes	Yes for Mageia 1 (by installer for Mageia 2)	Yes for Mageia 1 (by installer for Mageia 2)	No	No	No
tainted	No	No	No	No	No	No
debug/*	No	No	No	No	No	No

"Enabled by default" means that such a media is automatically registered, activated and used by the package manager for installing/updating software.

Now here are the media details:

core

• enabled by default
• mirrors must mirror this media to be listed as a mirror
• only free/libre stuff as described by FSF / OSI
• must be selfcontained

nonfree

• enabled by default for Mageia 1, disabled by default for Mageia 2 (installer will ask to enable it if it detects hw that need driver/fw from here...)
• mirrors must mirror this media to be listed as a mirror
• contains apps/drivers/firmware that are free to redistribute but we dont have redistributable source for
• for example ati/nvidia drivers/firmware, Oracle Java, ..

tainted

• disabled by default
• mirrors are free to not mirror this media
• stuff we think we can redistribute, but that may have some patent issues or other restrictions in other countries
• __NO__ nonfree stuff is allowed here
• see our Software patents policy and Software inclusion policy (drafts)

debug/core

• disabled by default
• debug rpms for core

debug/nonfree

• disabled by default
• debug rpms for nonfree

debug/tainted

• disabled by default
• debug rpms for tainted

Media layout details

Every media contains the same layout:

release

• disabled by default on nonfree, installer will ask to enable it if it detects hw that need driver/fw from here
• disabled by default on tainted, debug_core, debug_nonfree, debug_tainted

updates

• disabled by default on nonfree, installer will ask to enable it if it detects hw that need driver/fw from here
• disabled by default on tainted, debug_core, debug_nonfree, debug_tainted

updates_testing

disabled by default

backports

disabled by default

backports_testing

disabled by default

Mirrors layout

"distrib" section

• Hosts all source and compiled packages for all architectures, for cauldron (dev branch) and stable releases.
• Expected size:

"iso" section

• Hosts all released ISOs for cauldron (dev branch) and stable releases.
• Expected size:

"people" section

• Offers redundancy of a mirror space to Mageia members. We expect it to hold some specific flavor ISOs, or smaller files (rpms, tarball, document).
• this is part of a experiment to empower members to express themself
• Expected size:

"software" section

• Hosts tarballs of Mageia own hosted software (see soft/ section for now; forge to come).
• Expected size:

"archive" section?

Not defined yet. Would host unsupported/old releases (rpms/isos) for archiving purposes.

Full layout

And here is the full mirror layout: (stable releases have same layout as cauldron)

Remember that core, nonfree, tainted, debug/* have the same layout detail as shown above; this is omitted in the below tree for readability purpose.

How to (become a) mirror?

Prerequisites

• Expected size (700GB over 4 years?)
• Needed software (rsync)

Official sources

If you plan to create a public mirror, we encourage you to use one of our Tier1 mirrors:

* rsync://distro.ibiblio.org/mageia/ (Durham in the USA, slow sync)
* rsync://distrib-coffee.ipsl.jussieu.fr/mageia/ (Paris in France)
* rsync://ftp.LinuxCabal.org/Mageia (Lucern in Switzerland)
* rsync://mageia.c3sl.ufpr.br/mageia (Curitiba in Brazil)

These servers synchronise the tree directly from the Mageia rsync server (private access). Otherwise, you may use any of our [mirrors].

Rsync options

We would appreciate you use these options:

 $ rsync -aHS --delete-after 

-aH is a must. -S --delete-after are nice.

Please do not use compression and checksum options as these are too much a burden for the remote servers.

Automate

The tree must be synchronized at least every 2 hours.

Please ensure that another rsync process is not started before the first one has finished running: use a lock file.
