# We need a copy of the devstack repo to query for the list of image
|
|
# files to cached by the source-repositories element (see
|
|
# 55-cache-devstack-repos)
|
|
#
|
|
# This script is a hack to use the source-repositories repo cache to
|
|
# get early access to the devstack checkout (rather than doing a whole
|
|
# separate clone of the devstack tree). In essence, this script knows
|
|
# the path of the devstack in the source-repositories cache and
|
|
# creates/updates it. To get the gist of where this comes from, see
|
|
# dib's
|
|
# elements/source-repositories/extra-data.d/98-source-repositories
|
|
#
|
|
# This could be removed if we could ever source and call the
|
|
# clone/update functions asynchronously from the source-repositories
|
|
# dib element.
