This reverts commit a1bc8cb52c.
Please see resolv.conf(5) search domains must be on the same line. If
you use multiple seach key words only the last one is used. I tested this
with alpine and it works correctly when they are on the same line so I
am not sure what issues Dan had with it but this is not correct.
