Add etc/profile.d/disk-usage-warning.sh (POSIX sh) that warns in bold red at login when / or /home cross 85% usage. Deployed system-wide via install_disk_warning() (sudo install -D -m 0644), gated inside the apt-get block since df --output=pcent and /etc/profile.d are GNU/Debian conventions absent on macOS. Idempotent and re-runnable. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CN1KSmsuLG6TxSeN5m8xvM
