# Generation of the model:
|
|
# * At https://github.com/canonical/models one can find a repo of raw,
|
|
# unsigned, input .json files, and their signed .model equivalents.
|
|
# * At least once per cycle, update the json for the new Ubuntu version.
|
|
# To do this, take the previous cycle ubuntu-classic-$ver-amd64.json file,
|
|
# rename for the new version, and do any necessary updates including fixing
|
|
# the versions of tracks.
|
|
# * When this is done, the json needs to be signed. This needs to be done by
|
|
# a Canonical employee - try asking someone who has recently opened PRs on
|
|
# https://github.com/canonical/models with the signed models.
|
|
# * Ensure the signed and unsigned version of the models are updated in the
|
|
# models repo.
|
|
# * The signed model can then be placed here in livecd-rootfs at
|
|
# live-build/${PROJECT}/ubuntu-classic-amd64.model
