Why
Rsyslog's test suite and documentation used a mix of the bash-specific
"source" command and the portable POSIX "." command. This inconsistency
caused issues with repo-policy checks and potential portability
concerns.
Impact
Testing and documentation. All test wrappers in tests/ and guidance
in READMEs and skills now consistently use the POSIX standard.
Before/After
Before: 200+ files used "source", others used ".".
After: "source" is replaced by "." for script inclusion across the
repository. Repo-policy checks are tightened to enforce this.
