The former is a short hand for the latter and is already widely used in the docs. Using the short hand avoids incompatibility with the alternate impl of rst2html5. Reviewed-by: Erik Skultety <eskultet@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>

SYNOPSIS
virtlogd [OPTION]...
DESCRIPTION
The virtlogd program is a server side daemon component of the libvirt virtualization management system that is used to manage logs from virtual machine consoles.
This daemon is not used directly by libvirt client applications, rather it is called on their behalf by libvirtd. By maintaining the logs in a standalone daemon, the main libvirtd daemon can be restarted without risk of losing logs. The virtlogd daemon has the ability to re-exec() itself upon receiving SIGUSR1, to allow live upgrades without downtime.
The virtlogd daemon listens for requests on a local Unix domain socket.
OPTIONS
-h, --help
Display command line help usage then exit.
-d, --daemon
Run as a daemon and write PID file.
-f, --config FILE
Use this configuration file, overriding the default value.
-t, --timeout SECONDS
Automatically shutdown after SECONDS have elapsed with no active console log.
-p, --pid-file FILE
Use this name for the PID file, overriding the default value.
-v, --verbose
Enable output of verbose messages.
-V, --version
Display version information then exit.
SIGNALS
On receipt of SIGUSR1, virtlogd will re-exec() its binary, while maintaining all current logs and clients. This allows for live upgrades of the virtlogd service.
FILES
When run as root
@SYSCONFDIR@/libvirt/virtlogd.conf
The default configuration file used by virtlogd, unless overridden on the command line using the -f | --config option.
@RUNSTATEDIR@/libvirt/virtlogd-sock
The sockets virtlogd will use.
@RUNSTATEDIR@/virtlogd.pid
The PID file to use, unless overridden by the -p | --pid-file option.
When run as non-root
$XDG_CONFIG_HOME/libvirt/virtlogd.conf
The default configuration file used by virtlogd, unless overridden on the command line using the -f | --config option.
$XDG_RUNTIME_DIR/libvirt/virtlogd-sock
The socket virtlogd will use.
$XDG_RUNTIME_DIR/libvirt/virtlogd.pid
The PID file to use, unless overridden by the -p | --pid-file option.
If $XDG_CONFIG_HOME is not set in your environment, virtlogd will use $HOME/.config
If $XDG_RUNTIME_DIR is not set in your environment, virtlogd will use $HOME/.cache
EXAMPLES
To retrieve the version of virtlogd:
# virtlogd --version
virtlogd (libvirt) 1.1.1To start virtlogd, instructing it to daemonize and create a PID file:
# virtlogd -d
# ls -la @RUNSTATEDIR@/virtlogd.pid
