Right now syscons(4) uses a cons25-style terminal emulator. The
disadvantages of that are:
- Little compatibility with embedded devices with serial interfaces.
- Bad bandwidth efficiency, mainly because of the lack of scrolling
regions.
- A very hard transition path to support for modern character sets like
UTF-8.
Our terminal emulation library, libteken, has been supporting
xterm-style terminal emulation for months, so flip the switch and make
everyone use an xterm-style console driver.
I still have to enable this on i386. Right now pc98 and i386 share the
same /etc/ttys file. I'm not going to switch pc98, because it uses its
own Kanji-capable cons25 emulator.
IMPORTANT: What to do if things go wrong (i.e. graphical artifacts):
- Run the application inside script(1), try to reduce the problem and
send me the log file.
- In the mean time, you can run `vidcontrol -T cons25' and `export
TERM=cons25' so you can run applications the same way you did before.
You can also build your kernel with `options TEKEN_CONS25' to make all
virtual terminals use the cons25 emulator by default.

o Comment out display of fortune by default.
o Synch root's .cshrc/.login and non-root's .cshrc/.login in terms of
gratuitous variables set (EDITOR).
o Remove some commented out variables set inconsistently or gratuitously,
such as Interviews settings, 8-bit German locale for root only.
o Synchronize comments in header, as well as references to appropriate man
pages.
o Remove MANPATH setting as apparently /etc/manpath.config does all that
already.
Similar changes probably need to be made in other dot.* files for root
and skel, as all of these files seem to set different aliases, environmental
variables, prompts, and have different semantics.
As a result of this patch, leaving aside the setting of a special prompt
for root, users of csh and tcsh should find similar environments when
logging in or su'ing to any account using that shell.

even simple things like md5 and ping aren't in your path. This patch
moves the custom root-path setting from .login to .cshrc, so that users
who su to root get a decent (and consistent) path. An appeal to change
/etc/login.conf to provide a decent path for all users seems to have been
vetoed for the time being. As a result, users will still, by default,
not find ping or md5 in their path. However, at least root gets a decent
default now.

thing to use it at startup, when you don't know if the user can
handle vi or not, but yet another thing to leave it as a permanent
land mine for root.
2. Put /usr/X11R6/bin in path; it makes getting the desktop up a lot easier.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Finally transform the "Don't login as root..." message to make it
clear that `su' is meant to be a command. Will save us a lot of
questions about the user named `su'. Make the message magically
disappear if the user did an ``su - root'', since it might be a bit
silly to ask him to perform an `su'...
dot.cshrc:
Remove the no-op `-g' options from the ls aliases, and replace them by
`-o'. This way, if root does an `ls -l', he will see the immutable
flag and (hopefully) not be too surprised about the "Permission
denied".
