Other Changing the password of a PEFS‑encrypted filesystem

[Kaminar]

I have an existing PEFS‑encrypted filesystem that I originally created with the following command:

pefs addchain -fZ -a aes256 filesystemdir

I would like to change the password. Is there a way to change the password, or is the only option to recreate the PEFS filesystem with a new password and copy the old content into the new location?
