MFC r287396:
It's 2015, and some people are still trying to use fdisk and then go asking what debug flags to set for GEOM to make it work. Advice them to use gpart(8) instead.
Something similar should probably done with disklabel, but I need to rewrite the disklabel examples first.

The purpose of this change to the FFS layout policy is to reduce the running time for a full fsck. It also reduces the random access time for large files and speeds the traversal time for directory tree walks.
The key idea is to reserve a small area in each cylinder group immediately following the inode blocks for the use of metadata, specifically indirect blocks and directory contents. The new policy is to preferentially place metadata in the metadata area and everything else in the blocks that follow the metadata area.
The size of this area can be set when creating a filesystem using newfs(8) or changed in an existing filesystem using tunefs(8). Both utilities use the `-k held-for-metadata-blocks' option to specify the amount of space to be held for metadata blocks in each cylinder group. By default, newfs(8) sets this area to half of minfree (typically 4% of the data area).
This work was inspired by a paper presented at Usenix's FAST '13: www.usenix.org/conference/fast13/ffsck-fast-file-system-checker
Details of this implementation appears in the April 2013 of ;login: www.usenix.org/publications/login/april-2013-volume-38-number-2. A copy of the April 2013 ;login: paper can also be downloaded from: www.mckusick.com/publications/faster_fsck.pdf.

Enable operation of newfs on plain files, which is useful when you want to prepare disk images for emulators (though 'makefs' in port can do something similar).
This relies on: + minor changes to pass the consistency checks even when working on a file;
+ an additional option, '-p partition' , to specify the disk partition to initialize;
+ some changes on the I/O routines to deal with partition offsets.
The latter was a bit tricky to implement, see the details in newfs.h: in newfs, I/O is done through libufs which assumes that the file descriptor refers to the whole partition. Introducing support for the offset in libufs would require a non-backward compatible change in the library, to be dealt with a version bump or with symbol versioning.
I felt both approaches to be overkill for this specific application, especially because there might be other changes to libufs that might become necessary in the near future.
So I used the following trick: - read access is always done by calling bread() directly, so we just add the offset in the (few) places that call bread(); - write access is done through bwrite() and sbwrite(), which in turn calls bwrite(). To avoid rewriting sbwrite(), we supply our own version of bwrite() here, which takes precedence over the version in libufs.

MFp4:
Add a new option to newfs(8), -r, to specify reserved space at the end of the device. It can be useful, e.g., when the device is to become a member of a gmirror array later w/o losing the file system on it.
Document the new option in the manpage.
While I'm here, improve error handling for -s option, which is syntactically similar to -r; and document the fact that -s0 selects the default fs size explicitly, which can be useful, e.g., in a menu-based wrapper around newfs(8) requiring some value be entered for the fs size.
Also fix a small typo in the help line for -s (missing space).

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.

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).

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.

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.

Forced commit to give more details on what the patch does (sorry).
Instead of using 22 as the default cylinders per cylinder group parameter (the max. value for a 8k/1k FS), compute the maximum value allowed and use it. It can be overridden by specifying -c of course. This allow for FS built through the initial installation to have better values.

Change the defaults for newfs to disregard the geometry in the disklabel.
We pretend we have one head with two megabyte worth of sectors per cylinder.
The code try to access another head in what it belives to the same physical cylinder, because it belives that it would be faster than waiting for the next free sector under this head to come around.
Most modern drives doesn't have a "classical" geometry, and thus we end up fooling ourselves doing the above optimization. With this change we will fill a cylinder sequentially if we can, and thus get much more mileage from the track-buffer/cache built into the drives.
As a result a lot of seeks to the next or previous track should be avoided by this.
(My disk is a lot less noisy actually...)
You can still get the old behaviour, by specifying zero for the numbers.
This will also solve the problem with newfs barfing at really big drives.
