It obtuse and clueless except for a later statement the says search and domain are mutually exclusive, using the last option found.
As to what you put in the search line, I haven't a clue. I modified mine to: nameserver 192.168.XX.1 search coyote.den nameserver And ANAICT it made zero difference as it still Just Works(TM). Someone else has pointed out that this is actually controlled by nsswitch.conf, which contains: # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed, try: # `info libc "Name Service Switch"' for information about this file. passwd: compat group: compat shadow: compat hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis And while I'd not call that man page language swahili, it may be slightly better than the man page for resolv.conf. The operative line above may be the "hosts:" line. I'll leave the study of that man page for those search for a solution to a problem they are having. I'll note that the debian wheezy supplied file is quite heavily modified when compared to the example file in that man page. But no clue as to what problems the modifications are intended to fix. There may be more info in the ChangeLog.gz for these two files. I know roughly where those are, but have been up to my eyeballs in a 60 yo 1kw Gates am radio transmitter the last 2 days, and out of this loop. The real secret here is that I am of a dying breed in the broadcast world, I am one of the folks who actually go on call to fix things like transmitters. Most field engineers just pick up the phone and order a new one, for anything from 10G's for a 50 watt nighttime transmitter, to a couple million $ for a modern digital tv transmitter. This one has quite extensive damage to the audio driver pcb brought on by it being on a phenolic substrate, and the OEM solder was the same stuff RCA used in their TV's circa 1953-54. Darned near pure lead with a need to be heated and diluted with more modern, 250F lower melting temp solder before it can be removed to gain access to the component lead, 1/4" of which was bent over, locking it firmly to the board even if the solder was melted. The end result of course is copper traces lifted from the board by the excessive heat and loaded with microscopic cracks. I replaced several old carbon composition resistors that were way out of tolerance, but the final "fix" was a piece of 22 gauge wire connecting the two ends of a trace carrying 500 volt on the theory that if the trace was broken someplace in the middle, it was now being fed on both sides of the break. And it worked. That faint thumping you can hear in the background, is me pecking on wood for good luck. A new circuit board has been checked on, it would have to be made, min order 3 for around $11,000. So we cobble this one up yet one more time. But I'm likely both writing swahili to most of you, and boring the whole list.
