Comment # 13 on bug 1222314 from Michael Andres

The changed setup in YAST fooled me. The settings are not reset. AFAICS it
worked as expected.

An excerpt from the log:

> 2024-04-04 04:55:37 [zypp] RequestedLocalesFile.cc(load):51 Read /var/lib/zypp/RequestedLocales{- 0644 0/0 size 6}
> 2024-04-04 04:55:48 [zypp::satpool] PoolImpl.cc(setTextLocale):477 pool_set_languages: (en_US, en)

Apparently the instsys had "en_US" (size 6) in /var/lib/zypp/RequestedLocales.

Here YAST set "de_DE". The former "en_US" is gone. "de_DE" and it's fallbacks
were passed to the resolver.

The above fooled me. But Apparently YAST no longer does initializeTarget("/")
for the instsys when refreshing the repos. Repo refresh must determine the
requested locales (with respect to --root) to download localized repo metadata.
If a Target for "/" would have been initialized, the Target would have cached
the settings. Without this it reads them directly from
(/)var/lib/zypp/RequestedLocales for each repo.

But this does not alter the setting in the pool!

In every solver run i see the jobs to add the language supporting packages.

An finally in commit /mnt/var/lib/zypp/RequestedLocales was written (size 70).

Given the expected RequestedLocales would look like this:
> ma@hobbes:tmp (0)> cat /tmp/MNT/var/lib/zypp/RequestedLocales
> # zypp::RequestedLocales generated Thu Apr  4 11:11:47 2024

it would have size 70
