How to Manage several profiles in one laptop?
After I install Sabayon last night, I find that there is a big trouble to me.
My laptop works in several situations, DHCP and static IP, wired and wireless.
So, in my old system, Archlinux, I set several profiles for each situations. It would show a menu for me to select which profiles to use, before login.
There are other ways to solve the problem in ubuntu with its networkmanager, and in PCLinuxOS with its profiles manager. But after I read most the post in this Network board, it seems a big trouble in Sabayon.
Looking forwords to the solutions.
Thanks.
