PEFS is a kernel driver to offer userland encryption, to allow users to encrypt their own directories.
See https://pefs.io/ for more information.
As stated in D3389, the version of PEFS kernel module in the binary package is always an issue. Until now, the OS simply refused to load the kernel, but this time, it crashed the OS when running kldload pefs.
When loading afterwards the version compiled from the ports against our correct kernel version, everything is fine.
So we should always build it through ports.
