| 7 | UFS OPTIONS |
| 8 | =========== |

| 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. |
