Debian测试下如何挂载ufs文件系统？

为了将我的/dev/sda4 系统安装/mnt/ufs_mount在 Debian 测试上，我尝试了以下命令（它在 Debian Jessie 下工作正常）：

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

和：

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

但我收到这个错误：

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.

的输出dmesg | tail： :

[ 1136.965142] ufs: ufs_fill_super(): bad magic number
[ 1255.758946] ufs: ufs_fill_super(): bad magic number

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

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

和uname -a：

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

根据linux下挂载freebsd slice分区，您可能需要指定分区的偏移量。

partx -l应该能够识别文件系统的扇区偏移量，您需要将其乘以 512。您可以使用-o offset=$((512*sector_offset))- 假设您正在使用bash或类似的 shell 将其作为安装选项传递。
