Esta herramienta permite salvar el estado de uno o varios procesos y luego reanudar el trabajo desde la posici\u00f3n guardada, incluso despu\u00e9s de reiniciar el sistema o en otro servidor sin interrumpir las conexiones de red ya establecidas. El c\u00f3digo del proyecto se distribuye bajo la licencia GPLv2.    <\/p>\n<p>Entre las \u00e1reas de aplicaci\u00f3n de la tecnolog\u00eda CRIU se encuentra la posibilidad de reiniciar el sistema operativo sin interrumpir la continuidad de la ejecuci\u00f3n de procesos de larga duraci\u00f3n, la migraci\u00f3n en vivo de contenedores aislados, la aceleraci\u00f3n del inicio de procesos lentos (se puede empezar a trabajar desde un estado guardado despu\u00e9s de la inicializaci\u00f3n), la realizaci\u00f3n de actualizaciones del n\u00facleo sin reiniciar servicios, el salvado peri\u00f3dico del estado de tareas computacionales de larga duraci\u00f3n para reanudar el trabajo en caso de fallos, la balanceo de carga en nodos en cl\u00fasteres, la duplicaci\u00f3n de procesos en otra m\u00e1quina (fork en un sistema remoto), la creaci\u00f3n de instant\u00e1neas de aplicaciones de usuario en funcionamiento para su an\u00e1lisis en otro sistema o en caso de que se necesite deshacer acciones futuras en el programa. CRIU se aplica en sistemas de gesti\u00f3n de contenedores como OpenVZ, LXC\/LXD y Docker. Los cambios necesarios para el funcionamiento de CRIU est\u00e1n incluidos en la composici\u00f3n principal del n\u00facleo de Linux.      <\/p>\n<p>En esta nueva versi\u00f3n:  <\/p>\n<ul>\n<li class=\"l\"> Se ha a\u00f1adido el comando criu-ns, que permite restaurar una instant\u00e1nea guardada de un proceso con un nuevo identificador PID y en un espacio de nombres de montaje separado (mount namespace). La ejecuci\u00f3n con un PID diferente puede ser necesaria, por ejemplo, si el antiguo PID ya est\u00e1 en uso en el sistema.\n<li class=\"l\"> Se ha implementado la posibilidad de guardar y restaurar instant\u00e1neas del estado de perfiles anidados de apparmor.\n<li class=\"l\"> Se ha implementado la capacidad de bloquear y desbloquear recursos de red basados en nftables.\n<li class=\"l\"> Se ha a\u00f1adido soporte para la restauraci\u00f3n de dispositivos veth previamente creados.\n<li class=\"l\"> Se ha mejorado el soporte para la restauraci\u00f3n de contenedores en pods existentes.\n<li class=\"l\"> Para los clientes RPC, se ha a\u00f1adido la capacidad de determinar la reutilizaci\u00f3n de PID, implementada mediante el mecanismo pidfd.\n<li class=\"l\"> La licencia de todos los archivos proto en el directorio images\/ ha sido cambiada a MIT.      <\/ul>\n<p>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
