I am not sure what you mean by earlier.

The first thing executed when activating a major-mode is (according to
define-derived-mode) kill-all-local-variables which consist of

  run_hook (Qchange_major_mode_hook);
  reset_buffer_local_variables (current_buffer, 0);
  bset_update_mode_line (current_buffer);

Having 'permanent-local variables will only affect
change-major-mode-hook. I know no other hook ran earlier.

Why not instead add something that is run _after_
kill-all-local-variables? Then, there will be no need to fiddle with
'permanently-local (which might have undesired side effects).

Best,
Ihor
