Vagrant NFS share doesn't show updated file if size doesn't change

Solution 1:

This was bugging me for months, and I finally found a fix, if you're using Sublime Text (I'm on ST3). Check to see if it's using atomic saves — they were causing this issue for me.

To your Preferences.sublime-settings file, (Sublime Text > Preferences > Settings- User) add this:

{
    "atomic_save": false
}

This fixed the cached file-size NFS issue for us. Still unsure whether the root issue is in the OS X NFS daemon or the Ubuntu client (my money's on OS X).
