I suggest the latter, as it's a lot smaller and less likely to go wrong.
Red Hat distributes /usr/share/zoneinfo/leapseconds, whereas Ubuntu distributes
/usr/share/zoneinfo/leap-seconds.list. These have the same leap-second info but
use different formats; leapseconds is input suitable for zic, whereas
leap-seconds.list is the format that the NIST uses. I don't know why GNU/Linux
distributions differ in this area. I hope Apple chooses one format or the other
rather than going their own way.
