Using UFS — The Linux Kernel 5.18.5-gnu-1 documentation

# Using UFS

mount -t ufs -o ufstype=type_of_ufs device dir

## UFS Options

ufstype=type_of_ufs

  UFS is a file system widely used in different operating systems. The problem are differences among implementations. Features of some implementations are undocumented, so its hard to recognize type of ufs automatically. That’s why user must specify type of ufs manually by mount option ufstype. Possible values are:

  old

    old format of ufs default value, supported as read-only

  44bsd

    used in FreeBSD, NetBSD, OpenBSD supported as read-write

  ufs2

    used in FreeBSD 5.x supported as read-write

  5xbsd

    synonym for ufs2

  sun

  sunx86

    used in SunOS for Intel (Solarisx86) supported as read-write

  hp
