# This script will set up and run rsyncd to allow data to move into and out of

# our dockerized build system. This is used for syncing sources and changes of

|
|
# When run as root (rare) it'll preserve the file ids as sent from the client.
|

# Usually it'll be run as non-dockerized UID/GID and end up translating all file
