I think everybody could be satisfied by a small semantic redefinition of
the meaning of Link records.
The current practice seems to be:
1. Link records in the main files indicate that a given zone's data are
also used for an area in another country.
Example in file europe
Link Europe/Belgrade Europe/Ljubljana # Slovenia
Link Europe/Belgrade Europe/Podgorica # Montenegro
Link Europe/Belgrade Europe/Sarajevo # Bosnia and Herzegovina
Link Europe/Belgrade Europe/Skopje # North Macedonia
Link Europe/Belgrade Europe/Zagreb # Croatia
Example in file Africa
Link Africa/Abidjan Africa/Bamako # Mali
Link Africa/Abidjan Africa/Banjul # Gambia
Link Africa/Abidjan Africa/Conakry # Guinea
Link Africa/Abidjan Africa/Dakar # Senegal
Link Africa/Abidjan Africa/Freetown # Sierra Leone
Link Africa/Abidjan Africa/Lome # Togo
Link Africa/Abidjan Africa/Nouakchott # Mauritania
Link Africa/Abidjan Africa/Ouagadougou # Burkina Faso
Link Africa/Abidjan Atlantic/St_Helena # St Helena
2. Link records in file backward
# This file provides links between current names for timezones
# and their old names. Many names changed in late 1993.
Link Asia/Kolkata Asia/Calcutta
If the meaning of Link records in the main files were expanded to also
alternative zone names, then an entry in file europe
# alternative zone name Europe/Kyiv
Link Europe/Kiev Europe/Kyiv
would satisfy the Ukrainian requests.
Such a link results automatically in the creation of a zoneinfo file
Europe/Kyiv which is identical to Europe/Kiev
