59cf6deb68 Move the check for the ending char in the partition name where
it was before -- the check is only made when getdisklabel()
returns valid info.
On passing, use MAXPARTITIONS to identify the max partition number,
instead of the hardwired 'h'

64c8fef580 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.

9a6378d803 Rename the undocumented -E option to -X.
Implement -E option which will erase the filesystem sectors before
making the new filesystem.  Reserved space in front of the superblock
(bootcode) is not erased.

NB: Erasing can take as long time as writing every sector sequentially.

This is relevant for all flash based disks which use wearlevelling.

3249f70d0f - Pay attention to the fact that ioctl(2) is only known to
return -1 on error while any other return value from it can
indicate success.  (See RETURN VALUE in our ioctl(2) manpage
and the POSIX spec.)

- Avoid assumptions about the state of the data buffer after
ioctl(2) failure.

35956d32df 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).

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.

fc903aa525 Convert newfs to libufs (really). Solves one real issue with previous
version of such.  Differences in filesystems generated were found to be
from 1) sbwrite with the "all" parameter 2) removal of writecache.  The
sbwrite call was made to perform as the original version, and otherwise
this was checked against a version of newfs with the write cache removed.

that the kernel will refuse to mount. Specifically it now enforces
the MAXBSIZE blocksize limit. This update also fixes a problem where
newfs could segment fault if the selected fragment size was too large.

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).

9aba332745 Continue the cleanup preparations for UFS2 (& GEOM):
Use only one filedescriptor.  Open in R/O or R/W based in the '-N' option.
Make the filedescriptor a global variable instead of passing it around
as semi-global variable(s).

Remove the undocumented ability to specify type without '-T' option.

Replace fatal() with straight err(3)/errx(3).  Save calls to strerror()
where applicable.  Loose the progname variable.

Get the sense of the cpgflag test correct so we only issue warnings if
people specify cpg and can't get that.  It can be argued that this
should be an error.

Remove the check to see if the disk is mounted:  Open for writing
would fail if it were mounted.

Attempt to get the sectorsize and mediasize with the generic disk
ioctls, fall back to disklabel and /etc/disktab as we can.

Notice that on-disk labels still take precedence over /etc/disktab,
this is probably wrong, but not as wrong as the entire concept of
/etc/disktab is.

	-l hardware sector interleave
	-n number of distinguished rotational positions
	-p spare sectors per track

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.
