 | 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 |
