Subject: [PATCH] Make caching file for imporoving performance.

Previously, init.sh resize and check the filesystem every time.
It makes growing in booting time.
To reduce this, init.sh makes chache file for checking first boot or not.
Only when boot the first time, init.sh will resize and check the filesystem.
