[syslinux] PXE client does not honor "hostname" parameter passed by DHCP server

[a s p a s i a]

Hello all,

I would like to seek advise on the following;  I have configured linux
NFSroot images for a bunch of servers and am able to boot and run
stuff happily;  one nuance that bothers me is that, for instance, my
Fedora6 (x64) (kernel 2.6.22), (and noticed also in some other distros
- Fedora8, Ubuntu710), the client boots but DOES NOT seem to pick up
the hostname I pass it through the DCHP server.

1.  DHCP host declaration:

host r02s02 {
  hardware ethernet 00:A0:D1:E3:57:CA;
  fixed-address 192.168.16.12;
  filename "pxelinux.0";
  option host-name "r02s02";
}

2.  Client boots but NO hostname!

[root at localhost ~]# uname -a
Linux localhost.localdomain 2.6.22.custom.14 #1 SMP Thu Feb 28
11:35:58 PST 2008 x86_64 x86_64 x86_64 GNU/Linux
[root at localhost ~]# hostname
localhost.localdomain
[root at localhost ~]#

3.  my pxelinux.cfg configuration file is:
 cat 01-00-a0-d1-e3-57-ca
DEFAULT vmlinuz-2.6.22.custom.fc6
APPEND root=/dev/nfs rw
nfsroot=192.168.17.1:/export/images/00A0D1E357CA/fedora6_x64 ip=dhcp

Please advice if I am missing something perhaps?

thanks in advance!

Best regards,

- A.
