Cells for NetBSD: kernel-enforced, jail-like isolation

The latest update to NetBSD introduces kernel-enforced isolation, which allows processes to operate within confined environments, akin to jails. This architectural change aims to enhance system security significantly.

By creating these isolated environments, NetBSD improves resource management and stability across the system. This is particularly relevant for multi-tenant systems where security and performance are critical.

These enhancements are expected to have implications for system administrators and developers, as they may need to adapt their applications and infrastructure to leverage the new isolation capabilities effectively.
