ufs_vnops.c:
1) i_ino was confused with i_number, so the inode number passed to
VFS_VGET() was usually wrong (usually 0U).
2) ip was dereferenced after vgone() freed it, so the inode number
passed to VFS_VGET() was sometimes not even wrong.
Bug (1) was usually fatal in ext2_mknod(), since ext2fs doesn't have
space for inode 0 on the disk; ino_to_fsba() subtracts 1 from the
inode number, so inode number 0U gives a way out of bounds array
index. Bug(1) was usually harmless in ufs_mknod(); ino_to_fsba()
doesn't subtract 1, and VFS_VGET() reads suitable garbage (all 0's?)
from the disk for the invalid inode number 0U; ufs_mknod() returns
a wrong vnode, but most callers just vput() it; the correct vnode is
eventually obtained by an implicit VFS_VGET() just like it used to be.
Bug (2) usually doesn't happen.

Note: More work is needed in uipc_syscalls.c, but it will have to wait until

CDs.
With audio CDs, you can't just do a READ(10) call on most drives without
first setting the blocksize with a mode select command. The disklabel code
does a read of the first sector of the media to find a label if it exists.
This caused drives to return an error when an audio CD was in the drive,
due to the problem described above.
The solution is to read the table of contents on the CD, and only attempt
to read the disklabel if the first track is a data track.
This works on all the various CD and DVD media I have tried, but further
testing (especially with Video CDs and other mode 2 media) will be
needed to determine if this is a universal solution.
When this feature is enabled, mke2fs doesn't necessarily allocate a
super block and its associated descriptor blocks for every group.
The (non-)allocations are reflected in the block bitmap. Since the
filesystem code doesn't write to these blocks except for the first
superblock, all it has to do to support them is to not count them in
ext2_statfs() and not attempt to check them at mount time in
ext2_check_blocks_bitmap() (the check has never been enabled in
FreeBSD anyway).

This has now been added in the following way:
* Harness the make header file that's specified with the -h argument:
- Allow the user to define $(OPTS) to specify make arguments that should
be added to every program target.
- Allow the user to define $(prog_OPTS) to specify make arguments that
should just be added to the build of 'prog'.
* Make sure that $(OPTS) and $(prog_OPTS) are defined when looking through
each program's make file to determine which object files to crunch.
* When building the crunchgen makefile add $(OPTS) and $(prog_OPTS)
to the depend and build rules for $(prog_OBJS).

try to move the file from the source to the destination (spool) directory.
If that succeeds, much time and disk-space will be saved by doing that
instead of copying the entire file only to remove the original. This
could be a big win on machines doing samba-service or CAP-based printing.
Note that this is about the fourth or fifth iteration of the patch, after
trying to address all possible security implications of the change.

these global settings back out into the individual builds as OPTS, and
then migrate OPTS and prog_OPTS back into the local crunch.inc file.
