Hi,
I have desktop with 10-alpha2 (before BIND_* removal) and laptop/another
box with alpha3/11-CURRENT
All 3 boxes have the same /etc/resolv.conf:
# Generated by resolvconf
search minsk.domain
nameserver 192.168.9.250
nameserver 192.168.9.1
192.168.9.1 haven't named running, I forget to remove it from dhcpd.conf
long time ago.
today I became interested why my laptop(and box with CURRENT) resolves
names so long (drill(1)), i.e. running command `drill domain.tld` give
me result after.. ~15sec ( ^t - load: 0.59 cmd: drill 6852 [select]
15.09r 0.00u 0.00s 0% 3956k)
