Description

systemd-ssh-issue is a small tool that generates (when called with make-vsock) and removes (when called with rm-vsock) a /run/issue.d/50-ssh-vsock.issue drop-in file in case AF_VSOCK support is available in the kernel and the VM environment. The file contains brief information about how to contact the local system via SSH-over-AF_VSOCK, in particular it reports the system's AF_VSOCK CID. The file is typically read and displayed by agetty(8) on console or serial login prompts.

This tool is automatically used by systemd-ssh-generator(8) in the AF_VSOCK socket units it generates.

Options

The following options are understood:

--issue-path=
Changes the path to the issue file to write to/remove. If not specified, defaults to /run/issue.d/50-ssh-vsock.issue. If specified as empty string or - writes the issue file contents to standard output.

Exit status

On success, 0 is returned, a non-zero failure code otherwise.
