/usr/lib/systemd/systemd-ssh-issue [Options...] rm-vsock

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​.

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​.

Added in version 258​.

-h,  --help

Print a short help text and exit​.

--version

Print a short version string and exit​.

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