#!/usr/bin/env bash

# Synchronize two photo folders using rsync.
# * Handles moves by:
#    1. See if a file to be synched is already on target (with the same name)
#    2. If file is already on target, compare checksums.
#     2a- If checksums match, it was a file move, so delete file from target
#     2b- If checksums don't match, we are possibly talking about different files
# * Deletions are not synchronized to keep all files on target

• Install vagrant-vbguest
• vagrant ssh to the machine, and install Guest Additions manualy

• If all the previous fails, vagrant ssh to the machine, yum update and then try to install Guest Additions again
