I've been allowing dhclient-script (8), dhclient.conf (5), and dhcpd-options (5) to wear ruts in my brain to little avail. I have not been able to find anything that invokes dhclient.script, but the doc seems to indicate you should be able to create an /etc/dhclient-enter-hooks script (as well as an exit version if desired) where presumably you could do this customization.
Like I said, I have not found anything invoking /etc/dhclient-script, but it does exist. The hooks scripts do not currently exist on my system but a directory /etc/dhclient-enter-hooks.d apparently (see another post I just did for why I say apparently) does. The dhclient-script looks to me like it would run scripts in that directory if they were there (though my script skills are super rusty these days). In any case, this appears like a road to a solution though I do not know if the mechanism is the same for other distros. For that matter, I am not even sure for Ubuntu given that I can't yet determine that it actually uses /etc/dhclient-script.

You would think so wouldn't you? Seems like you 'should' be able to just
tell it to send /etc/hostname..... Or it should just do this by default
which it doesn't. At one point I saw a script to pull this off in a
hackish manner. But I haven't figured out how to get it to do the way it
seems like it should work. Personally I have dhcpd and bind setup with a
stub zone from my public domain for my local segment. For my static leases
assigned by mac it sending the hostname or not doesn't matter, but for the
dynamic pool that also has ddns setup on it. This is a problem if the
thing doesn't send the hostname. It'll still work just fine without it but
an A record doesn't get created in the forward and reverse zones without
it.
Its not something thats limited to a linksys dhcp feature. It shows up
everywhere. I haven't looked too hard but if you figure out how to make it
send /etc/hostname or something along those lines... Let me know.
