INSTALL-KEYMAP(8)           System Manager's Manual          INSTALL-KEYMAP(8)



NAME
       install-keymap  --  expand  a  given keymap and install it as boot-time
       keymap

SYNOPSIS
       install-keymap [keymap-name | NONE | KERNEL]

DESCRIPTION
       install-keymap usually takes a keymap-name as argument.   The  file  is
       passed  to loadkeys for loading, so that valid values for this argument
       are the same  than  that  of  arguments  to  loadkeys.   install-keymap
       expands  include-like  statements  in that file, and puts the result in
       /etc/console/boottime.kmap.gz, which will be loaded into the kernel  at
       boot-time.

       One may also specify KERNEL instead of a keymap name, causing /etc/con-
       sole/boottime.kmap.gz     to be removed, making  sure  that  no  custom
       keymap will replace the kernel's builtin keymap at next reboot.

       An argument of NONE tells the command to do nothing.  It can be used by
       caller scripts to avoid  handling  this  special  case  and  needlessly
       duplicate code.

       The  purpose  of  this processing is to solve an annoying problem, of 2
       apparently conflicting issues.  The first one is an important  goal  of
       keymap  management in Debian, namely ensuring that whenever the user or
       admin is expected to use the keyboard, the keymap selected as boot-time
       keymap is in use; this means the keymap has to be loaded before a shell
       is ever proposed, which means very early in the  booting  process,  and
       especially     before     all    local    filesystems    are    mounted
       (/etc/rcS.d/S10checkroot.sh can spawn sulogin).

       The second issue  is  that  for  flexibility  we  allow  that  /usr  or
       /usr/share   may   live   on   their   own   partition(s),   and   thus
       /usr/share/keymaps, where keymap files live, may not be  available  for
       reading at the time we need a keymap file.  And no, we won't put 1Mb of
       keymaps in the root partition just for this.

       And the problem is, most keymap files are  not  self-contained,  so  it
       does  not  help to just copy the selected file into the root partition.
       The best known solution so far is to expand the keymap file so that  it
       becomes  self-contained, and put it in the root partition.  That's what
       this tool does.
