Centos DHCP Group Declaration Alternative
 

Hi ,
I'm a Linux newbie so excuse my questions.

I have a client that created a Group Declaration for a few servers in our DHCP configuration (etc/dhcp/dhcpd.conf file)

the goal of the group is to exclude those servers from others and preform a small script on them (to pull ipxe script).

My question is:
is there an alternative way to do this group outside the DHCPD file?
My issue is to prevent clients from accessing the DHCP server to configure these settings.

Thanks in advanced
