I want to rename the my home directory (
/Users/thisone), using this technique.
However, I just started using Time Machine, and with 200 GB of data in my home directory; what will happen?
Will the entire 200 GB have to be backed up again, because Time Machine doesn't understand that the data is the same since the home folder name changed?
If so, as a panic resort, can I tamper with the Time Machine backup, renaming the home folder there too? (I have only a single backup so far).
If so, how do I do this? I seem to remember that even with
sudo, OS X objects to any change in the Time Machine folder.
