15. Procedures

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

15.1 Udeb Uploads

Before commiting releases of a udeb in d-i svn, one has to call:

   $ ../../scripts/l10n/output-l10n-changes . -d

15.2 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:

  • A mirror containing the released versions for the debian, debian-security and debian-volatile archive which the debian-live buildd can access.
  • The names of the image need to be known (e.g. debian-live-VERSION-ARCH-FLAVOUR.iso).
  • The packagelists need to have been updated.
  • The data from debian-cd needs to be synced (udeb exclude lists).
  • The includes from debian-cd needs to be synced (README.*, doc/*, etc.).
  • Images are built and mirrored on cdimage.debian.org.
  • 15.3 Point Releases

  • Again, we need updated mirror of debian, debian-security and debian-volatile.
  • Images are built and mirrored on cdimage.debian.org.
  • Send announcement mail.
  • 15.3.1 Point release announcement template

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

       $ sed \
           -e 's|%major%|5.0|g' \
           -e 's|%minor%|5.0.2|g' \
           -e 's|%codename%|lenny|g' \
           -e 's|%release_mail%|2009/msg00007.html|g'

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