>Environment:
Architecture: i386
Machine: i386
>Description:
Mounting a FFS filesystem on a 4k-sector disk fails when you run
i386/GENERIC, it works fine with i386/MONOLITHIC.

The reason is that i386/GENERIC uses ffs as a module which is
built with APPLE_UFS compatibility, while this is disabled in
the MONOLITHIC kernel.

Since such a label cannot be simply read from a 4k-sector disk,
the mount operation aborts with an error.

>How-To-Repeat:
Boot i386/GENERIC, create a FFS filesystem on a 4k-sector disk
and try to mount it.

>Fix:
Make APPLE_UFS fail gracefully when the label cannot be read.

>Release-Note:

State-Changed-Why:
The bug was fixed with ffs_vfsops.c 1.265


>Unformatted:

 sys/ufs/ffs/ffs_vfsops.c 1.265:
 Don't abort when APPLE_UFS autodetection cannot read the apple ufs label
 due to sector size or alignment problems. Autodetection is only a safety
 measure, you should mark the filesystem type in the BSD disklabel.
