AWS directoryservice documentation change

Service: directoryservice · 2025-11-22 · Documentation low

File: directoryservice/latest/admin-guide/join_linux_instance.md

Summary

Removed 'AWS' prefix from references to 'Directory Service-provided DNS servers' in configuration steps for multiple Linux distributions (Amazon Linux, CentOS, Red Hat, SUSE, Ubuntu).

Security assessment

The change appears to be a branding/naming convention update rather than addressing a security vulnerability. The modification only adjusts service naming consistency without altering technical instructions or security recommendations. DNS configuration guidance remains functionally identical, and there is no evidence of a security incident or vulnerability being addressed.
