Geez this is ugly. If that's the way it is, then I'll just write a
replacement for host to work sensibly.
If this is the designed behavior of the host command, then host will
hang anytime DNS is stopped.
Very bad.

Title:
Ubuntu 10.10 /etc/hosts ignored by /lib/resolv.so.2

ping works as expected...
root@net1# strace -e open /bin/ping localhost 21
open(/etc/ld.so.cache, O_RDONLY) = 3
open(/lib/libc.so.6, O_RDONLY)= 3
open(/etc/resolv.conf, O_RDONLY) = 4
open(/etc/resolv.conf, O_RDONLY) = 4
open(/etc/nsswitch.conf, O_RDONLY)= 4
The 'host' command is not reading /etc/hosts by design.
The command:
host foo dns-server
performs a dns lookup of host 'foo' from dns-server. If dns-server is not
provided, as in:
host foo
then, per the man page:
server is an optional argument which is either the name or IP address
