The sysutils/fusefs-lkl port may now be installed from pkg or ports. LKL ("Linux Kernel as a Library") is a special "architecture" of the full Linux kernel which builds as a userspace library on various platforms, including FreeBSD. One application of such a library is using Linux's filesystem drivers to implement a FUSE backend. fusefs-lkl's 'lklfuse' binary is such a FUSE filesystem. It can mount ext4/3/2, XFS, and BTRFS read-write, using the native drivers from Linux.
