Starting in Drupal 8, installation profiles can live under subdirectories under
profiles/. These might commonly be
profiles/custom. Provision doesn't currently recurse into subdirs when searching for profiles, and so these are missed.
A good example of a platform that does this is Thunder.
Original bug report by SocialNicheGuru:
I am not sure if this is only my install
I import a platform
The sites were imported
I imported the databases
But the only profile in the profiles directory that can be read is standard
I have openatrium in the profiles directory with 'chmod -R 777 openatrium' and the system does not read the folder at all.
