MOD_WEB, MOD_CAM, MOD_UI, MOD_SSH and MOD_WIFI all defaulted to on, and what
each one really offered was a half-installed printer: Mainsail with no
moonraker behind it, a camera that would not stream, a screen dark on purpose,
a root password deliberately not set on a machine whose entire recovery story
is "ssh in". Nobody wants those states. What someone who sets one actually
wants is a stock printer, and that is one FlashForge package away.
What they cost was a second answer to every question. Each init script carried
a gate, each `down` file argued its existence from a flag rather than from the
ordering that was the real reason, and anvil.conf had five lines that told a
user they had a choice.
MOD_SSH was the clearest case: it never turned ssh off. dropbear is the
rootfs's own and listens either way, so all the flag did was decline to set a
password.
Each gate is replaced by the fact it was standing in front of, not by a
constant:
S60nginx, S62moonraker nothing -- the web stack is what this mod is
S65camera there is no video device, which the script already
finds out and reports
S50wifi there is no $WIFI_CONF, likewise
S80ui HelixScreen is not installed, which was already the
other half of the condition
To leave a piece out, leave it out: BUILD_MAINSAIL, BUILD_MOONRAKER and
BUILD_HELIX decide what goes into a build, and `opkg remove` decides what stays
on a printer. What survives in anvil.conf is what has a range rather than a
state -- MOD_CAM_RES/FPS/PORT and the NICE_* priorities -- plus MOD_SPLASH,
MOD_STARTUP, MOD_IMPORT and MOD_S6, which are untouched here.
The `down` files stay. They were argued from MOD_WEB and MOD_CAM, but the
argument never depended on them: s6-svscan starts a service the instant the
directory appears, which is before any init script has checked a prerequisite.
Their text now says so.
Measured: `make build` produces a payload with no live read of any of the five,
and qa-static is 265 passed with shellcheck over the edited init scripts. The
test suite still exercises the removed flags and has not been updated.
