# Check for changes needed by the container image. Two flavours of images are
|
|
# supported, namely 'test' and 'devel'.
|
|
#
|
|
# Usage: scripts/container-needs-rebuild.sh {test|devel} [git-since]
|
|
#
|
|
# - flavour is either 'test' or 'devel'
|
|
# - the optional 'git-since' points to a git reference, 'origin/master' if
|
|
# not set
|
|
#
|
|
# Returns 0 in case changes do not affect the container image.
|
|
# Returns 10 in case the changes need a rebuild of the container image.
