ln -s will still "work" (giving a broken link) even if the file you want to link to does not exist. I realized this when deploying oxnotes-docservices. I wanted to create a systemd .service file for my unicorn server and so my script ran
sudo ln -fs /home/ubuntu/oxnotes-docservices/config/deploy/unicorn.service /etc/systemd/system
However, when I looked at the /etc/systemd/system/unicorn.service link by running cat it said the file was not found. The issue was that the source dir to ln did not even exist - it was missing the current folder between oxnotes-docservices and config
I fixed in a general way by adding a test -f SOURCE && before my ln command.
