12*4882a593Smuzhiyun	UFS is a file system widely used in different operating systems.
13*4882a593Smuzhiyun	The problem are differences among implementations. Features of
14*4882a593Smuzhiyun	some implementations are undocumented, so its hard to recognize
15*4882a593Smuzhiyun	type of ufs automatically. That's why user must specify type of
16*4882a593Smuzhiyun	ufs manually by mount option ufstype. Possible values are:
