NAME
systemd-ssh-issue - Generator for SSH login prompt drop-ins
SYNOPSIS
/usr/lib/systemd/systemd-ssh-issue [OPTIONS...] make-vsock
/usr/lib/systemd/systemd-ssh-issue [OPTIONS...] rm-vsock
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

--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.
