Before we had a posix_openpt() that allocated PTY's with proper
permissions in place, we used this set-uid utility to change the
ownership of PTY slave devices to the real user ID of the process. This
utility was used to implement grantpt().
In my first designs of the MPSAFE TTY layer, I replaced this by adding
an ioctl() called TIOCGRANTPT, which was used to change the ownership.
I left the pt_chown utility, because older C libraries needed it to work
properly.
After some discussions back in June I changed the PTY code to set
permissions properly upon creation. Fortunately the previous grantpt()
implementation changed permissions by hand when pt_chown is not
installed, which always succeeds. This means grantpt() still works
properly, even though the set-uid utility is missing.
I've done tests with FreeBSD 5.2.1, FreeBSD 6.3 and FreeBSD 7.0 jails.
All of them still work if I remove pt_chown.

The last half year I've been working on a replacement TTY layer for the
FreeBSD kernel. The new TTY layer was designed to improve the following:
- Improved driver model:
The old TTY layer has a driver model that is not abstract enough to
make it friendly to use. A good example is the output path, where the
device drivers directly access the output buffers. This means that an
in-kernel PPP implementation must always convert network buffers into
TTY buffers.
If a PPP implementation would be built on top of the new TTY layer
(still needs a hooks layer, though), it would allow the PPP
implementation to directly hand the data to the TTY driver.
- Improved hotplugging:
With the old TTY layer, it isn't entirely safe to destroy TTY's from
the system. This implementation has a two-step destructing design,
where the driver first abandons the TTY. After all threads have left
the TTY, the TTY layer calls a routine in the driver, which can be
used to free resources (unit numbers, etc).
The pts(4) driver also implements this feature, which means
posix_openpt() will now return PTY's that are created on the fly.
- Improved performance:
One of the major improvements is the per-TTY mutex, which is expected
to improve scalability when compared to the old Giant locking.
Another change is the unbuffered copying to userspace, which is both
used on TTY device nodes and PTY masters.
Upgrading should be quite straightforward. Unlike previous versions,
existing kernel configuration files do not need to be changed, except
when they reference device drivers that are listed in UPDATING.

MPSAFE patches on current@ and stable@. This driver also has a fundamental
issue in that it sleeps when sending commands to the card including in the

such, the driver shouldn't be working reliably even on 4.x.
current@ and stable@ for the locking patches. The driver can always be
revived if someone tests it.
This driver also sleeps in its if_init routine, so it likely doesn't really
work at all anyway in modern releases.
sgtty was the original interface to configure terminal attributes on my
UNIX-like operating systems. It has been deprecated by the POSIX termios
interface, which is implemented in almost any modern system.
An advantage of turning this into a binary compatibility interface, is
that we can now eventually remove the COMPAT_43TTY switch from kernel
configurations. This removes many ioctl()'s from the TTY layer.
While there, increase the __FreeBSD_version, which may be useful for the
people working on the Ports tree.

with fortunes and fortunes2 2 years and 2 days ago. The fortunes2-o
file was brought in with the original import of the 4.4 Lite games
directory, but has always consisted in large part of fortunes
duplicated from other files.
The combined size of the two files is still only 631K, or less
than 1/3rd of the size of the fortunes file.
Combining them has the added benefit of making the fortunes from
fortunes2-o visibile to fortune(6)'s -m option.
This change should probably not be MFC'ed beyond RELENG_7.

The head of the file ObsoleteFiles.inc contains instructions how to add
obsolete files/dirs/libs to the list. Obviously one should add obsolete
files to this list, when he removes a file/dir/lib from the basesystem.
Additionally add check-old target:
- allows re@ to check if a file on the obsolete list resurfaces
Design goals:
- allows full control by the user (default interactive mode)
- possibility of scripted removal of obsolete files (batch mode)
- opt-in removal of files (explicit list of files)
- seperate removal of libs (2 delete targets)
Important design decissions:
- structured list of files to remove instead of a plain text file:
* allows to remove additional files if a NO_foo knob is specified
without the need to change the targets (no NO_foo knob is respected
yet)
- not using mtree like NetBSD does:
* mtree doesn't has an interactive mode
