>Description:
	Our mount(8) man page says under description of the
	relatively recently added "log" feature/option:

	   (FFS only with UFS2 superblock layout)

	However, the newfs(8) man page does not mention the
	UFS2 text string, under description of the "-O" option
	the text says

               0    4.3BSD; This option is primarily used to build
                    root file systems that can be understood by older
                    boot ROMs.
               1    FFSv1; normal fast-filesystem (default).
               2    FFSv2; enhanced fast-filesystem (suited for more
                    than 1 Terabyte capacity, access control lists).

	Someone muttered that the UFS2 / FFSv2 confusion is something
	we have imported from elsewhere.  However, we should not
	contribute to it, and should provide for a little more smooth
	sailing when users want to enable the "log" feature.

>How-To-Repeat:
	Inspect our mount(8) and newfs(8) man pages.
>Fix:
	No textual suggestion provided here.

 "UFS2 superblock layout" is description about superblock, not FS itself.
 UFS1 (or FFSv1) can have UFS2 layout superblock.

 I think the description of newfs(8) has been updated in -current.

 Hmm, to split hairs...  Do we have any tools which create an UFS2
 layout superblock but create an FFSv1 file system?  If not, then
 I'll claim that the distinction is ... slightly academic.

 Ah, yes, I should have checked that before submitting.  It's a
 lot better in -current -- it's possible to navigate from the
 mount(8) man page via the information in the newfs(8) man page
 and end up with using the apparently correct "-O 2" option to
 newfs.

 Yes, that is what you end up with when you do a new install and select
 FFSv1.

 Yes, it's the default.

 I had thought that tunefs could update the superblock type, and you
 needed to do this if you had an ancient fs, but now I can't see any
 evidence of this in either tunefs.8 or tunefs.c. What am I missing?
 (anyone? please fix the commented out chunk of mount.8 that I just
 committed...)

 "fsck_ffs -c 4" as mentioned in wapbl(4),
 but newer newfs(8) creates it by default, I think.

 Oh, fsck_ffs(8) does mention only FFSv2, not UFS2...
