We have a similar requirement which I¹m sad to say is being worked around
with wait code. We can¹t know the list of bundles/features which will be
deployed and required ahead of time. Our ETL application runs
transformations after startup which may contain steps provided by plugins
(deployed as bundles). When can the application be certain that the Karaf
environment is fully initialized, all features have been installed and
FileInstall has done a pass over the configured directories? Today if the
step component isn¹t available we loop/wait for a configurable timeout
then fail if it hasn¹t become available.
