include statement

[Hai Tao]

a strange thing happened:
   
  I created /etc/subnets/ to hold all my subnet files
  and in my dhcpd.conf
  include "/etc/subnets/1"
  include "/etc/subnets/2"
   
  I also config the /etc/sysconfig/dhcpd, partially as
   
  DHCPD_CONF_INCLUDE_FILES="/etc/dhcpsubnets"
   
  when I start dhcpd by using rcdhcpd start the first time, /etc/dhcpd.conf and /etc/subnets/* were copied to /var/lib/dhcp/etc/.
   
  then, I added a subnet file under /etc/subnets/, include the file in /etc/dhcpd.conf, and restart the service the second time by using rcdhcpd restart. what happened is that I was told that the new subnet file could not be found. I checked the /var/lib/dhcp/etc/, and found there is a new subnets folder under the existing /var/lib/dhcp/etc/subnets/, containing all the subnet files.but the new added subnet file was not copied to the existing /var/lib/dhcp/etc/subnets/.
   
  Is there any idea that I can get through this? My purpose is to make config change in /etc/dhcpd.conf and /etc/subnets/, and restart by using rcdhcpd to make it take effect.

I don't know for sure on SLES 10. However, on SLES 9, the configuration 
for DHCPD is in /etc/sysconfig/dhcpd. In that file is a section like:


## Type: yesno
## Default: yes
## ServiceRestart: dhcpd
#
# Shall the DHCP server dhcpd run in a chroot jail (/var/lib/dhcp)?
#
# Each time you start dhcpd with the init script, /etc/dhcpd.conf will
# be copied to /var/lib/dhcp/etc/.
#
# Some files that are important for hostname to IP address resolution
# (/etc/{hosts,host.conf,resolv.conf,localtime}, /lib/libnss_dns.so.2,
# /lib/libresolv.so.2) will also be copied to the chroot jail by the
# init script when you start it (about 100kB altogether).
#
# The pid file will be in /var/lib/dhcp/var/run/dhcpd.pid.
#
DHCPD_RUN_CHROOTED="yes"


So in this situation, your include would have to be below /var/lib/dhcp 
and the path would have to be relative to it. 

For example, if your include file is /var/lib/dhcp/etc/include, then the 
dhcpd.conf file would include /etc/include.
