Allow cross-type communication
Sending notifications is possible from
- manifest
- gencode-local
- gencode-remote
Sending a notification from an object means writing to the file "notifications" into
its object:
echo mytest >> "$__object/notifications" # a type reports something
Reading / Reacting on notifications works by accessing the file
referred to be "$__notifications". All notifications are prefixed with
the object name ($__object_name) and are appended into this file.
To find out, whether a file was copied, run:
grep __file/etc/passwd:copy "$__notifications"
