Relationship Between Bootc and OSTree
The A/D bits exist entirely for the operating system's benefit. The Accessed bit tells the OS which pages have been recently used, enabling page replacement algorithms to choose pages to evict when memory runs low.

Trade-offThe trade-off versus gVisor is that microVMs have higher per-instance overhead but stronger, hardware-enforced isolation. For CI systems and sandbox platforms where you create thousands of short-lived environments, the boot time and memory overhead add up. For long-lived, high-security workloads, the hardware boundary is worth it.
