When `/etc/hosts` contained a FQDN with a trailing dot, the `\b` in the sed expression would not match, since dot is not considered to be a word character. Fix this by regexp-escaping the hostname search, and matching the end of the line on optional space followed by additional characters. Also add some tests that extract the regexp used by sed and verify that it does what we want. These will hopefully serve us in the future if we ever need to test additional edge cases. |
