| # There is a race condition with chromeos_shutdown (b/267224195) that causes |
| # swap_management to be killed by process_killer before it can properly process |
| # a D-Bus message here. To avoid this and ensure that zram swap stops, we run |
| # swap_management directly instead of using dbus-send. |
| # Once the issue above is resolved, we should consider using D-Bus messages. |
