Como ativar o suporte ao sistema de arquivos Unix no kernel do Linux? [duplicado]

Question

Depois de mudar do Debian estável para o teste Debian eu tenho um problema para montar minha partição root do FreeBSD no meu sistema: Como montar o sistema de arquivos ufs no teste Debian?

Eu descubro quais sistemas de arquivos meu kernel Linux suporta através deste comando cat /proc/filesystems :

nodev   sysfs
nodev   rootfs
nodev   ramfs
nodev   bdev
nodev   proc
nodev   cpuset
nodev   cgroup
nodev   cgroup2
nodev   tmpfs
nodev   devtmpfs
nodev   debugfs
nodev   tracefs
nodev   securityfs
nodev   sockfs
nodev   bpf
nodev   pipefs
nodev   hugetlbfs
nodev   devpts
nodev   pstore
nodev   mqueue
    ext3
    ext2
    ext4
nodev   autofs
    btrfs

Por padrão, o kernel do Linux não pode ler / gravar na partição FreeBSD-ufs .

Como ativar o suporte ao sistema de arquivos Unix ( ufs ) no kernel do Linux?

Atualizar

a saída de:

modprobe ufs
mount -t ufs -o ufstype=ufs2 /dev/sda4 /mnt/ufs_mount

é:

mount: /dev/sda4 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sda4,
missing codepage or helper program, or other error

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

A saída de dmesg | tail :

   [ 1136.965142] ufs: ufs_fill_super(): bad magic number
[ 1255.758946] ufs: ufs_fill_super(): bad magic number
[ 2098.945757] ufs: ufs was compiled with read-only support, can't be mounted as read-write
[ 2098.946045] ufs: You didn't specify the type of your ufs filesystem

      mount -t ufs -o ufstype=sun|sunx86|44bsd|ufs2|5xbsd|old|hp|nextstep|nextstep-cd|openstep ...

      >>>WARNING<<< Wrong ufstype may corrupt your filesystem, default is ufstype=old
[ 2098.967212] ufs: ufs_fill_super(): bad magic number
[ 2927.982112] perf: interrupt took too long (2504 > 2500), lowering kernel.perf_event_max_sample_rate to 79750

Meu sources.list :

deb http://httpredir.debian.org/debian/ stretch main
deb-src http://httpredir.debian.org/debian/ stretch main

deb http://security.debian.org/debian-security stretch/updates main

e uname -a :

Linux debian 4.6.0-1-amd64 #1 SMP Debian 4.6.4-1 (2016-07-18) x86_64 GNU/Linux

Usando um kernel debian padrão?

Teste modprobe ufs como raiz para carregar o suporte ao sistema de arquivos UFS.
