# Based on setupcon, but stripped down for use in a udev rule.
# We have to do several basic things here, each of which has specific state
# requirements:
#
# 1) Set Unicode/non-Unicode mode on each virtual console.
#
# The terminal line emulation on the virtual console must not be in raw
# mode (as in cfmakeraw).
#
# 2) Set the font and ACM on each virtual console.
#
# The virtual console must not be in KD_GRAPHICS mode. If using vgacon,
# the *foreground* virtual console must not be in KD_GRAPHICS mode either
# as then we'll corrupt video memory.
#
# 3) Set the keyboard mode on each virtual console to K_XLATE or K_UNICODE
# as appropriate.
#
# The virtual console must not be in K_RAW or K_MEDIUMRAW mode.
#
# We don't have to set the console keymap here. This only needs to be done
# once after setting the keyboard mode, so it belongs in an Upstart job
# instead.
