Brain fart on guard clauses when I've been using them all this time...
Updating the conditions made the ternary fall out of favor.
Changed some wording in the doc to suggest the domain name for a
particular NIS server may be different from the bootparamd client's
configuration.
Looks like I can't decide on certain style preferences.
Not keen on using blank?, but I've used it before. Time to commit?
Also, fail_with has been fixed for aux and post since #8643. Use it!
