# `panama update`: the routine command, and the promises that make it routine.
#
# An update that asks questions is an update nobody runs, and a machine nobody
# updates drifts until the next reinstall. So the properties below are the
# whole point of the command rather than details of it:
#
# 1. --upgrade NEVER runs the interview. This is the regression that started
# the redesign: ./install asked the full first-install questionnaire every
# time, including on a machine whose answers could not have changed.
# 2. --upgrade runs exactly the stages that need no answer, and never
# setup-identity or install-hardware. Both act only on interview answers.
# 3. install-packages is gated on a content hash of the package lists, and
# the hash is NOT recorded when the stage fails -- the same rule
# panama-migrate applies to its markers, for the same reason.
# 4. A conflicted `git stash pop` leaves no conflict markers in the tree.
# Every dotfile here is a symlink into the checkout, so a half-merged file
# is not something to fix later: it is live in ~/.config immediately, and
# a broken .qml costs the running shell.
#
# Driven against fixture stages in a throwaway PANAMA_PATH, with sudo and
# gsettings shimmed, so this never touches the machine running it.
