CentOS - Mar 2009 - manage different profile with a laptop

Hi,
 
I need to use different profile with some linux CentOS  laptops.
 
- I need to connect the laptops at work  with NIS, automount, DHCP .... 
 
- The same laptops can be use at home without NIS etc..but with personal
wifi connection ....
 
- The same laptops can be use in travel without network configuration
 
Which best software to use to manage different profile ?
 
Regards.

Hi Rachid,
> I need to use different profile with some linux CentOS  laptops.
I'm managing such profiles with a custom init script.  The scripts 
checks what IP address (if any) the machine got and according to this 
address, I disable/enable some services (NIS, sendmail, automounter, 
local vs. remote homedirectories etc.).  It's not very elaborate but 
works fine until now.

Cheers
