dhcpd.conf, resolv.conf and the search directive

Hi folks quick question,

Is there any way to automatically populate resolv.conf with more than
one search domain.

Currently it is given the value of the domain-name option from
dhcpd.conf, but I need the resolver to search two domains for a hostname.

Write a script. run it whenever the system boots, or runs dhcp

Yes.

my preference was to remove the search line to speed up all the
external values.

do a
man (your_dhcp_client_daemon_here)
to see if it indicats a file which runs after it obtains a lease.
The script would be as simple as

echo "search whatever you like here" > /tmp/resolv.conf
grep -v search /etc/resolv.conf >> /tmp/resolv.conf
/bin/cp /tmp/resolv.conf /etc/resolv.conf

dude, instead of having two domains why dont you setup 2 subdomains
within a single domain?
and setup a small dns server with a single zone and a couple of
subdomains... or using /etc/hosts (if ip addresses are not dynamic)

Thanks people,
running a script after dhcpcd has run was going to be my preferred option.
I was just hoping there would be some neat little option in dhcpd.conf
that would populate resolv.conf fully.
Cheers again
