16. Procedures

This chapter documents the procedures within the Live Systems Project for various tasks that need cooperation with other teams in Debian.

16.1 Major Releases

Releasing a new stable major version of Debian includes a lot of different teams working together to make it happen. At some point, the Live team comes in and builds live system images. The requirements to do this are:

16.2 Point Releases

16.2.1 Last Point Release of a Debian Release

Remember to adjust both chroot and binary mirrors when building the last set of images for a Debian release after it has been moved away from ftp.debian.org to archive.debian.org. That way, old prebuilt live images are still useful without user modifications.

16.2.2 Point release announcement template

An announcement mail for point releases can be generated using the template below and the following command:

$ sed \
     -e 's|@MAJOR@|9.0|g' \
     -e 's|@MINOR@|9.0.1|g' \
     -e 's|@CODENAME@|stretch|g' \
     -e 's|@ANNOUNCE@|2017/msgXXXXX.html|g'

Please check the mail carefully before sending and pass it to others for proof-reading.

Updated Live @MAJOR@: @MINOR@ released

The Live Systems Project is pleased to announce the @MINOR@ update of the
Live images for the stable distribution Debian @MAJOR@ (codename "@CODENAME@").

The images are available for download at:

   <http://live-systems.org/cdimage/release/current/>

and later at:

   <http://cdimage.debian.org/cdimage/release/current-live/>

This update includes the changes of the Debian @MINOR@ release:

   <https://lists.debian.org/debian-announce/@ANNOUNCE@>

Additionally it includes the following Live-specific changes:

  * [INSERT LIVE-SPECIFIC CHANGE HERE]
