b459937e0c Throw the switch--change to UFS2 as our default file system format for
FreeBSD 5.1-RELEASE and later:

- newfs(8) will now create UFS2 file systems unless UFS1 is specifically
  requested (-O1).  To do this, I just twiddled the Oflag default.

- sysinstall(8) will now select UFS2 as the default layout for new
  file systems unless specifically requested (use '1' and '2' to change
  the file system layout in the disk labeler).  To do this, I inverted
  the ufs2 flag into a ufs1 flag, since ufs2 is now the default and
  ufs1 is the edge case.  There's a slight semantic change in the
  key behavior: '2' no longer toggles, it changes the selection to UFS2.

This is very similar to a patch David O'Brien sent me at one point, and
that I couldn't find.

1c85e6a35d This commit adds basic support for the UFS2 filesystem. The UFS2
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).

5dccd5c649 Swing the axe and remove some archaic features from newfs which modern
diskdrives do neither need nor want:

	-O create a 4.3BSD format filesystem
	-d rotational delay between contiguous blocks
	-k sector 0 skew, per track
	-l hardware sector interleave
	-n number of distinguished rotational positions
	-p spare sectors per track
	-r revolutions/minute
	-t tracks/cylinder
	-x spare sectors per cylinder

No change in the produced filesystem image unless one or more of
these options were used.

3626f83327 Update the default newfs block and fragment sizes from 8192/1024 to
16384/2048.

Following recent discussions on the -arch mailing list, involving dillon
and mckusick, this change parallels the one made over a decade ago when
the default was bumped up from 4096/512.

This should provide significant performance improvements for most
folks, less significant performance losses for a few folks and
wasted space lost to large fragments for many folks.

For discussion, please see the following thread in the -arch archive:

Subject: Using a larger block size on large filesystems

2441e154ef Correct the example introduced in rev 1.29, which suggested a block:frag
size ratio other than 8:1.  Currently, we only recommend an 8:1
ratio, because the impact of others ratios has not been adequately
investigated.

Also, do not recommend the use of the -c option in the example, since
newfs now automatically calculates the best cyl:cylgrp ratio.

This change was discussed with the author of rev 1.29.
