filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.
Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.
Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

affect current systems until fsck is modified to use these new
facilities. To try out this change, set the fsck passno to zero
in /etc/fstab to cause the filesystem to be mounted without running
fsck, then run `fsck_ffs -p -B <filesystem>' after the system has
been brought up multiuser to run a background cleanup on <filesystem>.
Note that the <filesystem> in question must have soft updates enabled.

Second part of the fsck wrappers commit. This commit enables the new fsck
code (removing the fsck/* code and replacing it with the netbsd fsck
wrapper code), and enabling some FFS-based utilities to compile.
Details:
* quotacheck, fsdb required modification to use the fsck_ffs/ code rather
than fsck/ . This might change later since quotacheck requires preen.c
which should exist in fsck/ rather than fsck_ffs/
* src/Makefile has fsck_ffs added to it so it it built as part of the tree
now
* share/doc/smm/03.fsck/ uses the SMM.doc/ stuff from fsck_ffs, not fsck.
I've tested this, and it shouldn't require any changes on your machine.
The fsck wrapper reads /etc/fsck and is command-line-compatible enough
to not require rc changes (well, most changes unless you want to do
anything nifty by specifying the fs types explicityly, read the man page
if you want further details on what it can do.)
This now allows us to support multiple filesystem types during bootup.

The beginnings of the fsck wrappers stuff from NetBSD. This particular commit
brings a newly repo-copied sbin/fsck_ffs/ (from sbin/fsck/) into fsck wrappers
mode.
A quick overview (the code reflects this):
* Documentation changed to reflect fsck_ffs instead of fsck
* Simply acts on a single filesystem, doesn't try to do any multiple filesystem
magic - this is done by the fsck wrappers now
And then specific to fsck_ffs:
* link to /sbin/fsck_4.2bsd and /sbin/fsck_ufs. This is because right now
the filesystem is of type ufs not ffs, and that during autodetection the
labeltype rather than the VFS type is used - this is because when doing
an autodetection of filesystem type in the fsck wrapper program, it does
not have any link between label type (4.2bsd, vinum, etc) and VFS string.
Note that this shouldn't break a build since the required buildworld Makefile
magic and import of the fsck wrapper code into src/sbin/fsck/ will happen
in a seperate commit.

and an unknown uid/gid is found in the file system. This is useful
if you wind up with a file in your file system that has a uid
that is extremely large, since quotacheck will wind up running
a very very long time due to it not handling large gaps in uids
very well (this is a problem that should be addressed some day).
Update the man page to reflect that fact the the -v flag now prints
some additional diagnostic messages.
