With a good hardware reference clock \ +sub-microsecond accuracy is possible. \ +\ +Two programs are included in chrony: chronyd is a daemon that can be \ +started at boot time and chronyc is a command-line interface program \ +which can be used to monitor chronyd's performance and to change \ +various operating parameters whilst it is running. \ +\ +This recipe produces two binary packages: 'chrony' which contains chronyd, \ +the configuration file and the init script, and 'chronyc' which contains \ +the client program only." + +HOMEPAGE = "http://chrony.tuxfamily.org/" +SECTION = "net" +LICENSE = "GPLv2" +LIC_FILES_CHKSUM = "file://COPYING;md5=751419260aa954499f7abaabaa882bbe" + +SRC_URI = "https://download.tuxfamily.org/chrony/chrony-${PV}.tar.gz \ + file://chrony.conf \ + file://chronyd" +SRC_URI[md5sum] = "d0598aa8a9be8faccef9386f6fc0d5f2" +SRC_URI[sha256sum] = "8d04e7cda2333289c2104b731d39c3c1db94816e43bae35d7ee4e7ae8af6391f" + +DEPENDS = "pps-tools" + +# Note: Despite being built via './configure; make; make install', +# chrony does not use GNU Autotools. +inherit update-rc.d systemd + +# Configuration options: +# - For command line editing support in chronyc, you may specify either +# 'editline' or 'readline' but not both. editline is smaller, but +# many systems already have readline for other purposes so you might want +# to choose that instead.
