• set that folders to the blacklist in the build script https://github.com/joomla/joomla-cms/blob/staging/build/deleted_file_check.php

There shouldn't be a blacklist in that script. The entire intent is to write out a list of deleted files between any two git references. It's up to whomever is using the file that script generates to decide what to do with the data, which means reviewing it and not just copy/pasting the entire file into the com_admin script.

There needs to be a blacklist in my new script that i used to generate this however - because it's doing directory iterations https://github.com/joomla/joomla-cms/pull/25559/files

Is this supposed to solve #25531?

[SharkyKZ]

This is fine when updating between 4.0 versions. But not when upgrading from 3.x.

I experience this with J4 beta1-dev - after update folders are missing from com_config. A temporary solution is to copy com_config from an expanded package zip file.

Installation fixes will be solved by #25559 and com_config probably needs a better fix because on linux systems we won't clean up properly the old j3 directories after this is applied so closing this. com_config issue still needs to be solved and tracked in #25531

@wilsonge when we don't want to apply this workaround until we have a final version than please mention this issue in the release notes so everyone is aware of this issue.

#27481 com_config proper patch
