Functions
-
chroot (args, argv)
Run program in new root and namespaces.
$ space chroot --pid --uid '0 1000 1' ~/.local/share/lxc/ubuntu/rootfs/ /bin/ls /home/
Create a child process that executes a shell command in new root directory, ns, user and additional namespaces; allow UID and GID mappings to be specified when creating a user namespace.
Analog of chroot program.
-
Note: If the program you're trying to exec is dynamic linked, and the dynamic linker is not present in /lib in the chroot environment - you would get the
-
"OSError: [Errno 2] No such file or directory" error.
You'd need all the other files the dynamic-linked program depends on, including shared libraries and any essential configuration/table/etc in the new root directories.
