modules

• I don't think any modules removed in PR 65971 affect us.

states

From 65971:

• alias (core)
• alternatives (core)
• debconf (core)
• mysql_database (wordpress)
• mysql_grants (wordpress)
• mysql_user (wordpress)
• gem (redmine)
• rvm (redmine)
• svn (redmine)
• webutil (htpasswd)

Looks like postgres is saved for now.

The Redmine server will not last long term, so we can abandon it instead of upgrading, if needed.
