|  | 2 | ========= |

|  | 4 | mount -t ufs -o ufstype=type_of_ufs device dir | 
|  | 5 |  |

|  | 7 | UFS OPTIONS | 
|  | 8 | =========== | 
|  | 9 |  | 
|  | 10 | ufstype=type_of_ufs | 
|  | 11 | UFS is a file system widely used in different operating systems. | 
|  | 12 | The problem are differences among implementations. Features of | 
|  | 13 | some implementations are undocumented, so its hard to recognize | 
|  | 14 | type of ufs automatically. That's why user must specify type of | 
|  | 15 | ufs manually by mount option ufstype. Possible values are: | 
|  | 16 |  | 
|  | 17 | old	old format of ufs | 
|  | 18 | default value, supported as read-only | 
|  | 19 |  | 
|  | 20 | 44bsd	used in FreeBSD, NetBSD, OpenBSD | 
|  | 21 | supported as read-write | 
|  | 22 |  | 
|  | 23 | ufs2    used in FreeBSD 5.x | 
|  | 24 | supported as read-only | 
|  | 25 |  | 
|  | 26 | 5xbsd	synonym for ufs2 | 
|  | 27 |  | 
|  | 28 | sun	used in SunOS (Solaris) | 
|  | 29 | supported as read-write | 
|  | 30 |  | 
|  | 31 | sunx86	used in SunOS for Intel (Solarisx86) | 
|  | 32 | supported as read-write | 
|  | 33 |  | 
|  | 34 | hp	used in HP-UX | 
|  | 35 | supported as read-only | 
|  | 36 |  | 
|  | 37 | nextstep | 
|  | 38 | used in NextStep | 
|  | 39 | supported as read-only | 
|  | 40 |  | 
|  | 41 | nextstep-cd | 
|  | 42 | used for NextStep CDROMs (block_size == 2048) | 
|  | 43 | supported as read-only | 
|  | 44 |  | 
|  | 45 | openstep | 
|  | 46 | used in OpenStep | 
|  | 47 | supported as read-only | 
|  | 48 |  | 
|  | 49 |  | 
|  | 50 | POSSIBLE PROBLEMS | 
|  | 51 | ================= | 
|  | 52 |  | 
|  | 53 | There is still bug in reallocation of fragment, in file fs/ufs/balloc.c, | 
|  | 54 | line 364. But it seems working on current buffer cache configuration. |
