# ----------------------------------------
# 🗑️ Weekly Garbage Collection.
# ----------------------------------------

# Cleans unused packages every Monday at 4 PM, waiting 24+ hours after updates to avoid issues.
#
# ✅ What it does:
# • Runs: "nix-collect-garbage -d".
# • Deletes unused system generations and packages.
# • Frees up disk space safely.
#
# ⚠️ What it doesn't do:
# • ❌ Won't remove your currently active or booted system configuration.
# • ❌ Doesn't reboot your machine.

# 📝 Tip: Adjust the times below to fit your schedule or preferences.
