Are Linux containers stable enough for production and why Nexedi uses SlapOS nano-containers instead ?

Nexedi does not use LXC containers or docker because it is impossible to ensure their stable operation especially in case of kernel ABI mismatch or missing containerisation of system calls. Instead, we use SlapOS nano-containers which have provided since 2010 similar benefits in a more stable way while using less resources. SlapOS nano-containers will soon be deployed on embedded device using Elbe embedded Linux with over-the-air (OTA) upgrade and secure boot.
