>Environment:

>Description:
	On systems where /usr/share is NFS-mounted, running
	single-user means that /usr/share/misc/termcap is not
	available, and thus vi and emacs won't work.  We can put
	a small termcap in root's home directory to hopefully
	allow the use of vi etc.

>How-To-Repeat:
>Fix:
	Here's a bit of the needed work.  Someone familiar with
	the distribution/release build process can probably
	improve on this.  Also, I do not know what the console
	term types are for many of the archs, so the 'for' list
	needs to be expanded.

1.  Create a script /usr/src/etc/root/gentermcap that generates
the mini-termcap to stdout, using "tset".
------------------------------------------------
#!/bin/sh
#  Generate a miniature termcap, for use as root's .termcap
#  file.  This should have all of the basic console entries for the
#  various architectures.
#  We want to force tgetent() to look in a particular file.  According
#  to the man page, this should do it:
export TERM=totally_bogus
export TERMCAP=bogus_termcap_entry
export TERMPATH=../../share/termcap/termcap.src

version=`grep "^#.*Version" $TERMPATH`

echo "#  The purpose of this file is to provide essential termcap"
echo "#  entries, to be used e.g. when running single-user and the"
echo "#  full termcap database in /usr/share/misc/termcap isn't accessible."
echo "#  "
echo "#  This file was generated on "`date`", using termcap version:"
echo $version

for terms in vt100 vt220 pc3 pcvt25 \
	; do
	#  Ignore first line, and first word of second line.
	#  Note that simply printing $2 won't work, as some
	#  termcap aliases have spaces in their names.
	#  Also, strip leading space from result.
	tset - -S $terms \
		| awk '{ if (NR==2) {$1=""; print $0;}}' \
		| sed -e 's/^ //'
done

echo "#  Add any local essential terminal entries here, for when "
echo "#  /usr/share/misc/termcap isn't accessible."
------------------------------------------------

2.  Change the Makefile in /usr/src/etc to invoke the script.

3.  Add appropriate essential term names for the various ports.

4.  Add /root/.termcap to file lists for distributions.

5.  I'm sure there's more that I am missing...  :)

 To whomever actually decides to do this (this sent to make note in the
 PR database):

 this probably should add "sun", "vt52", "ansi-mini" (which is not vt100),
 "hpgeneric", "adm31" (includes Wyse 1xx), "wy30", and when I finally add it
 to the termcap.src, "ofcons" (for Shark support).

 This script should not have a set list of terminal types; it should
 key from the terminal type found on the console in /etc/ttys. The
 console is the only terminal which is most commonly in use in single
 user mode, but the kind of console one might have could be most
 anything in /etc/termcap, which makes it unwise to assume that vt100
 (or anything else) is the common case.

 Ideally, what you want is for the .login or .profile or .cshrc to
 make the /root/.termcap into a termcap cache...
