+ <para>
+ Make <application>initdb</application> examine
+ the <filename>/etc/localtime</filename> symbolic link, if that
+ exists, to break ties between equivalent names for the system time
+ zone. This makes <application>initdb</application> more likely to
+ select the time zone name that the user would expect when multiple
+ identical time zones exist. It will not change the behavior
+ if <filename>/etc/localtime</filename> is not a symlink to a zone
+ data file, nor if the time zone is determined from
+ the <envar>TZ</envar> environment variable.

<para>
- This makes <application>initdb</application> more likely to select
- the desired time zone string when multiple identical time zones
- exist.
+ Separately, prefer <literal>UTC</literal> over other spellings of
+ that time zone, when neither <envar>TZ</envar>
+ nor <filename>/etc/localtime</filename> provide a hint. This fixes
+ an annoyance introduced by <application>tzdata</application> 2019a's
+ change to make the <literal>UCT</literal> and <literal>UTC</literal>
+ zone names equivalent: <application>initdb</application> was then
+ preferring <literal>UCT</literal>, which almost nobody wants.
