For future reference, because for some reason this is difficult to Google (and find the correct answer):
To update a symlink without having to delete it and recreate it:
ln -sfn [source file] [target file]
Why the options sfn?
-s is for creating the symlink and not a hard link
-f is of course to force the update, since it already exists.
-n (or -h, they are the same) says not to follow the existing symlink
These options in combination allow a symlink to a directory to be updated in place.
