+You have run fmtutil-user (as opposed to fmtutil-sys) for the first time; this
+has created format files which are local to your personal account.
+
+Any changes in system formats will *not* be automatically reflected in
+your files; furthermore, running fmtutil-sys will no longer have any
+effect for you. As a consequence, you have to rerun fmtutil-user yourself
+after any change in the system directories.
+
+See http://tug.org/texlive/scripts-sys-user.html for details.
+
+If you want to undo this, remove the files mentioned above.
