12*34d5f4f2SShobhit Kukreti	UFS is a file system widely used in different operating systems.
13*34d5f4f2SShobhit Kukreti	The problem are differences among implementations. Features of
14*34d5f4f2SShobhit Kukreti	some implementations are undocumented, so its hard to recognize
15*34d5f4f2SShobhit Kukreti	type of ufs automatically. That's why user must specify type of
16*34d5f4f2SShobhit Kukreti	ufs manually by mount option ufstype. Possible values are:
