# Alloy console palette — point the Linux console's sixteen ANSI slots at Akari.
#
# The greeter (tuigreet, on VT1) runs on a raw Linux virtual console, before
# any Wayland session or terminal emulator exists. tuigreet can only name ANSI
# colors (container=white, text=black, prompt=yellow, ...), so the first
# surface a user sees on boot is themed entirely by what those sixteen console
# slots hold. Left alone they are the kernel's stock palette, and login renders
# in generic console colors that then jump into Akari at session start.
#
# setvtrgb rewrites the console color map, which is a single global map the VT
# subsystem shares across every console including ones allocated later, so one
# invocation before the first text surface is enough. The map file is generated
# at image-build time from the default light theme (skelgen, from the same ANSI
# table the kernel cmdline's vt.default_* arrays and the terminal emulator both
# render from); this unit only applies it.
#
# systemd-vconsole-setup owns the console font and keymap and does not touch
# the color map, so ordering after it is for cleanliness, not conflict. The
# Before= list covers every text surface that can paint on a console: greetd on
# VT1, and any getty (other VTs, and the alloy-debug-shell, which also orders
# before getty.target).
#
# Not yet verified on hardware: that setvtrgb, run from a unit with no
# controlling terminal, reaches the console it opens on this image, and that
# the greeter comes up on the Akari tones. Both are the live-boot checks the
# GoingsOn greeter task carries.

# The map is a pure build artifact and setvtrgb ships in kbd; if either is

# Containerfile exist to prevent. The conditions here keep the unit from
# failing loudly on a hand-modified image where they were removed.
