dhcp snippet (dhcp is not on here so hopefully this snippet is valid):
default-lease-time 21600;
subnet 10.202.46.0 netmask 255.255.255.0 {
use-host-decl-names on;
option log-servers 10.202.46.2;
host ws001 {
hardware ethernet 00:11:22:33:44:55;
fixed-address 192.168.0.1;
default-lease-time 10000
filename "/lts/vmlinuz-2.4.26-ltsp-1";
}
}
Here's the same thing in .ini style:
[global]
default-lease-time 21600
[10.202.46.0]
netmask 255.255.255.0
use-host-decl-names on
log-servers 10.202.46.2
[ws001]
subnet 10.202.46.0
hardware-ethernet 00:11:22:33:44:55
fixed-address 192.168.0.1
default-lease-time 10000
filename "/lts/vmlinuz-2.4.26-ltsp-1"
I'd argue that as the number of subnets and special case workstations
goes up, the ability of a system administrator to read and understand
the flat file is going to be markedly harder than for the admin to read
the custom-crafted dhcp-config syntax.
So if the end-goal is to keep the system-administrator's poor brain from
exploding while manually editing the files, I'd say custom-crafted
config files can be a win versus the generic one-size-fits-all approach.
