Bug#4258: kbd program can't use multiple sized fonts
Package: kbd
Version: 0.91-4
The kbd package config utility has a script called kbdconfig which can be
run to configure keyboard mapping and soft fonts. These settings are used
on boot by a script /etc/rc.boot/0kbd from a config file /etc/kbd/config.
Some of the fonts have multiple sizes (972.cp for example). When such a
font is selected, it is necessary to select which size is desired, for
example (setfont /usr/lib/kbd/consolefonts/972.cp -16) would specify size
16.
When such a font is selected by kbdconfig, no mechanism is provided to set
the font size in the boot script, so the font is not loaded.
# setfont /usr/lib/kbd/consolefonts/972.cp
This file contains 3 fonts: 8x8, 8x14 and 8x16. Please indicate
using an option -8 or -14 or -16 which one you want loaded.
#
I am using kernel 2.0.0, Debian 1.1 (unstable tree circa Jun 22 1996), and
libc5.2.18-8 and libc4.6.27-15.
----------------
I have made changes to the /usr/sbin/kbdconfig script to poll the user for
the font size if it is needed (and to save it in the config file), and to
ask the user if they want to enable the configuration when the script
completes.
I have also changed the /etc/rc.boot/0kbd file to use the font size value.
These are the patches ... I'm not familiar enough with diff/patch to give a
full-directory patch of the changes, so I am diff'ing them seperately.

-------------------------------
(Obviously change this in any way you want, all rights
UN-reserved ;)
The only thing I don't like about these changes is that kbdconfig runs
setfont to determine if the font needs a size specified. I don't know if
this could cause problems or not (ie on old vga/ega/cga/mga/hgc whatever),
but:
1) I don't see this as -introducing- a problem, since it only does it if you
specify a font, in which case that font would load on next boot anyway.
2) It does restore a hopefully readable default font after allowing the font
to be viewed, thus guarding against an (is this a possibility?) unviewable
font from being configured and going unnoticed.
In other words, it looks like a feature to me.
