[Bug 2008076] Re: Drop /usr/share/zoneinfo/posix and move /usr/share/zoneinfo/right into tzdata-legacy

[Benjamin Drung]

Hi Vincent, I uploaded chrony 4.3-1ubuntu3 to add the tzdata-legacy a
few hours ago.

Note: The leap seconds can also be read from /usr/share/zoneinfo/leap-
seconds.list

** Description changed:

  The tzdata package ships /usr/share/zoneinfo/posix/ (for Coordinated Universal Time) and /usr/share/zoneinfo/right/ (for International Atomic Time). The files in /usr/share/zoneinfo/posix/ are identical to their counterpart in /usr/share/zoneinfo/. The tzdata package converts the
  configured posix/* and right/* timezones to their unprefixed variant on every package upgrade (e.g. it changes "posix/Europe/Berlin" to "Europe/Berlin").
  
  Drop /usr/share/zoneinfo/right from tzdata and move
  /usr/share/zoneinfo/right into separate tzdata-legacy package.

  Two packages need to be adjusted:
  
+ * chrony: reads /usr/share/zoneinfo/right/UTC for leap seconds
  * moment-timezone.js: uses /usr/share/zoneinfo/posix/ in debian/rules
  * rdate: reads /usr/share/zoneinfo/right/UTC -> depend on tzdata-legacy
  
  Following packages were checked and do not need to be touched:
  
  Only in source code documentation and/or tests suite:
  
  * mariadb
  * mariadb-10.6
  
  Copies of tz soure code:
  
  * rust-chrono-tz (in tz)
  * udm (in tzdatabase)
  * r-cran-tzdb (in inst/tzdata)
  * pike8.0 (in lib/modules/Calendar.pmod/tzdata)
  
  Referencing only /usr/share/zoneinfo/posixrules:
  
  * manpages-l10n
  * libdatetime-timezone-perl
  * asterisk
  * mozjs102
  * mozjs78
  * thunderbird
