The actual syntax of nsswitch.conf is slightly different from the
current regular expression:
- A comment can appear anywhere, not just at the beginning of a
line.
- Action items take the general form [STATUS=ACTION] or
[!STATUS=ACTION] (with some optional whitespace).
- A service name cannot include a colon. This is a nitpick,
because there should never be more than a single colon per
line.
