== NAME
uuidd - UUID generation daemon
== SYNOPSIS
*uuidd* [options]
== DESCRIPTION
The *uuidd* daemon is used by the UUID library to generate universally unique identifiers (UUIDs), especially time-based UUIDs, in a secure and guaranteed-unique fashion, even in the face of large numbers of threads running on different CPUs trying to grab UUIDs.
Do not create a socket but instead expect it to be provided by the calling process. This implies *--no-fork* and *--no-pid*. This option is intended to be used only with *systemd*(1). It needs to be enabled with a configure option.
Make uuidd use this pathname for the unix-domain socket. By default, the pathname used is _{runstatedir}/uuidd/request_. This option is primarily for debugging purposes, since the pathname is hard-coded in the *libuuid* library.
