# Builds the amd64 headless audio-endpoint ISO (mini PC + USB DAC/amp) with
|
|
# live-build — the same tool tools/build-thin-client-iso.sh
|
|
# drives, reused here rather than a new toolchain, per
|
|
# hosts/audio-endpoint/README.md's reasoning. Unlike that image, this one has
|
|
# no graphical/kiosk stack at all: it boots straight to multi-user.target with
|
|
# the shared spotify-connect.service running.
|
|
#
|
|
# One build per room: unlike the arm64 image (one generic .img, per-room
|
|
# identity set later via Raspberry Pi Imager), there is no equivalent
|
|
# post-build customisation tool for a generic x86 ISO, so IMAGE_HOSTNAME below
|
|
# is baked in at build time — same convention as the thin client's own
|
|
# THINCLIENT_NAME/IMAGE_HOSTNAME. Re-run this script once per room, changing
