s6-rc's database is generated from anvil-core's etc/s6-rc/source, and the only thing that ran s6-rc-compile was the payload build. So `opkg upgrade anvil-core` on a printer wrote new service definitions and left the machine booting the database compiled from the old ones -- the upgrade landed and changed nothing. anvil-core ships bin/anvil-s6-rc-compile.sh and its postinst calls it. anvil-s6-rc calls it too, because s6-rc-compile writes its own execline shebang and oneshot runner into every database it produces, so one left by the previous s6-rc is not one this s6-rc should run. The payload build calls the same script rather than its own copy of the compile, passing the database name: given one the script prunes every other database, which is what keeps two builds of one commit byte-identical. Without a name it timestamps and keeps the database it replaced, so a printer that will not boot has one to point `current` back at. Nothing live is touched either way -- a running supervision tree keeps its database until the next boot, so an upgrade cannot restart services mid-print. anvil-s6-rc gains PKG_STAMP_EXTRA: its version comes from the tarball and cannot see control/postinst, and a stamp that cannot see an input reports "already current" and ships the previous .ipk.

# Two things an unpacked package is not enough for, both because what the
|
|
# printer reads is generated or symlinked rather than shipped:
|
|
#
|
|
# the boot path $MODDIR/prog/firmwareExe is a new file, and /usr/prog
|
|
# goes on running the copy it already had
|
|
# the boot database etc/s6-rc/source/ is text, and the database the last
|
|
# boot used was compiled from the PREVIOUS definitions --
|
|
# so a changed or added service would not reach the
|
|
# printer at all
|
|
#
|
|
# The same two scripts run from installer/runFirmwareExe.sh on the .tgz path.
|
|
# Their own guards are what make this a no-op when the build installs this
|
|
# package rather than a printer.
