Enroot vs LXC

Enroot is a free, open-source Linux command-line utility that turns traditional container and operating-system images into unprivileged sandboxes. It is aimed at high-performance or virtualized environments where portability and reproducibility matter and additional isolation is not required. Enroot runs without a daemon and supports unprivileged multi-user use without a setuid binary. Linux user and mount namespaces preserve filesystem separation, while the project provides little to no isolation. The command line covers batch, bundle, create, exec, export, import, list, remove, and start operations. It imports known formats including Docker, with the README reporting a 3x to 5x speedup for large Docker-image imports. Built-in GPU support uses libnvidia-container, and hooks can add NVIDIA support or Mellanox host MOFED. Runtime settings come from enroot.conf or higher-priority environment variables. Standard and hardened package flavors are available.

LXC is free software for creating and managing Linux system or application containers through Linux kernel containment features. It aims to make each container resemble a standard Linux installation without a separate kernel. The project includes the liblxc library, container control tools, distribution templates and API bindings for Python 3, Lua, Go, Ruby and Haskell. Process containment uses kernel namespaces, AppArmor and SELinux profiles, seccomp policies, chroots, kernel capabilities and cgroups. Unprivileged containers map container root to an unprivileged host user. LXC is included in most Linux distributions and is generally installed through the distribution package manager. Listed requirements include a supported C library and Linux kernel 2.6.32 or later. LXC 7.0 and 6.0 are listed as long-term support releases through June 1, 2031 and June 1, 2029. Most code uses GNU LGPLv2.1+, with some BSD 2-clause or GNU GPLv2 components.
