That is a extremely non-standard location for *any* access to leap-seconds.list 
from any system, and like anything else in tzdata, it could change or be 
dropped: it should at least be symlinked from /etc/?

Or some declaration needs to be specified somewhere:

RH chrony requires leapseclist:

	https://chrony-project.org/doc/4.7/chrony.conf.html#leapseclist

	leapseclist /usr/share/zoneinfo/leap-seconds.list

NTF ntpd defaults to and ntpsec requires leapfile:

	#leapfile   /etc/leap-seconds.list
