This prevents any change to the `/etc/subuid` and +`/etc/subgid` files from being propagated to the rootless containers +while the pause process is running. + +For these changes to be propagated, it is necessary to first stop all +running containers associated with the user and to also stop the pause +process and delete its pid file. Instead of doing it manually, `podman +system migrate` can be used to stop both the running containers and the +pause process. The `/etc/subuid` and `/etc/subgid` files can then be +edited or changed with usermod to recreate the user namespace with the +newly configured mappings. + +## OPTIONS + +**--new-runtime**=*runtime* + +Set a new OCI runtime for all containers. +This can be used after a system upgrade which changes the default OCI runtime to move all containers to the new runtime. +There are no guarantees that the containers will continue to work under the new runtime, as some runtimes support differing options and configurations. + +## SYNOPSIS +**podman system migrate** + +## SEE ALSO +`podman(1)`, `libpod.conf(5)`, `usermod(8)` + +## HISTORY +April 2019, Originally compiled by Giuseppe Scrivano (gscrivan at redhat dot com) |
