mount -t ufs -o ufstype=type_of_ufs device dir
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 format of ufs default value, supported as read-only
used in FreeBSD, NetBSD, OpenBSD supported as read-write
used in FreeBSD 5.x supported as read-write
synonym for ufs2
used in SunOS (Solaris) supported as read-write
used in SunOS for Intel (Solarisx86) supported as read-write
used in HP-UX supported as read-only
used in NextStep supported as read-only
used for NextStep CDROMs (block_size == 2048) supported as read-only
used in OpenStep supported as read-only
See next section, if you have any.
