Online RootFS growth
On growth-enabled images, Sandbox0 automatically expands the writable RootFS as free space runs low, within a configured sparse logical ceiling up to 64 TiB. Agent processes keep running. Growth is enabled in the qualified Cloud region; confirm activation for other regions. Existing images and snapshots retain their captured storage geometry. The ceiling is logical capacity, not preallocated host disk.
NAVER servers already preserve a complete OS disk during a supported retained lifecycle. The pricing and stop policy do not establish integrated automatic online low-space growth of that RootFS; verify disk and guest-filesystem expansion for the chosen generation.
