Supposedly you've been reading source more than me lately, but 
almost all the non-source documentation says that the resolver in 
modern libc (and this goes back 5 or more years) does not use 
/etc/host.conf.

I can see a need for a small libc as being more pressing in a 
router, and maybe libc in OpenWRT is more ancient than what Debian 
provides.  But, I can go dig through the code manually to see if 
libc in OpenWRT (a year ago) actually uses /etc/host.conf.  I have 
better things to do, but if this needs to get cleared up, I am 
willing to go reading source code.  But, if my entire ImageBuilder 
archive (of 1 year ago) has no need of /etc/host.conf, I think 
maintainers in Linux should consider removing it.  Because 
nsswitch.conf is supposed to be providing all that information.
