ostree-admin-init-fs - Man Page

ostree admin init-fs [Options...] {PATH}

Initialize an empty physical root filesystem in the designated PATH, with normal toplevels and correct permissions for each directory​. Primarily useful for operating system installers​.

--modern

Equivalent to --epoch=1​.

--epoch

This accepts an integer value in the range [0-1], inclusive​. The default is zero for compatibility​.

When set to 1, the command will skip adding a number of toplevel "API filesystems" such as /proc to the toplevel of the physical root​. These should be unnecessary, as they should only be mounted in the final deployment root​. The main exception is /boot, which may need to be mounted in some setups before the target root​.

Epoch 2 is the same as 1, except that the toplevel ostree directory is mode 0700, denying access from unprivileged code​. This is a new recommended best practice as it avoids access to old configuration files in /etc in previous deployments, as well as potentially old setuid binaries in /ostree/repo​.
