sometimes problem happens.

Now, This script works well.

I didn't notice zram-config syncs when it stops. This script is perfectly I wanted. Swap system doesn't work dynamic originally , therefore I also want to use zram as disk. But I thought this script doesn't sync . Much Thanks. I changed to use zram-swap-config zram-config.

:)

It works well and syncs with this setting.
