install.sh runs under `set -euo pipefail` and step 3 called uninstall.sh, which uses `sudo rm`. On a machine without cached or passwordless sudo that call fails, so the install aborted at step 3 -- after the package was installed and the timer enabled. It would report failure for an install that had actually worked, which is precisely the half-finished state the sudo-refusal guard at the top of the script exists to prevent. The vmbox harness could not have caught this: the guest's `arch` user has passwordless sudo, which is why the run went green. The cleanup is opportunistic -- a machine with no /usr/local/bin/shutdown needs nothing done -- so it is now non-fatal, gated on `sudo -n` so it cannot hang on a password prompt in a non-TTY context either. When it is skipped the script says why it matters and gives the exact command, rather than leaving the shutdown wrapper in place silently. Verified: uninstall.sh --retired-only and install.sh are both idempotent and exit 0 on a host where the retired pieces are already gone.

# Install the wake-alarm trigger timer.
|
|
#
|
|
# Usage: bash install.sh
|
|
#
|
|
# The PC no longer wakes anyone -- the phone does. All this installs is the
|
|
# per-minute trigger that starts morning-routine.service (and therefore the
|
|
# workout lock) at the time the phone last synced.
|
|
#
|
|
# What it does:
|
|
# 1. Installs wake_alarm + dependencies for /usr/bin/python
|
|
# 2. Installs the systemd user units and enables the per-minute trigger timer
|
|
# 3. Removes the retired waking machinery from earlier installs
|
|
#
|
|
# Deliberately NOT done any more, and why:
|
|
# - no shutdown wrapper, no rtcwake, no sleep hook: the PC does not wake you
|
|
# - the /etc/sudoers.d/wake-alarm entry is left ALONE. screen-locker's own
|
|
# _wake_alarm.py still shells out to `sudo rtcwake`, so removing it here
|
|
# would silently break a live feature in another repo.
|
|

|
|
# so `systemctl --user` fails and later steps are silently skipped while the
|
|
# earlier pip output still looks like success. It also runs pip as root, which
|
|
# leaves root-owned files in ~/.cache/pip. Failing loudly beats half-finishing.
