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.
OakHost already retains whole installed-system SSD state. Changing hardware capacity assigns a new Mac, while backups are a separate responsibility; this differs from integrated automatic online low-space growth of Sandbox0’s supported Linux RootFS.
