After intalling Arch Linux from tty until desktop environment several times I decided to install a very stable Linux distro, the grand daddy of a lot of distribution including Linux Mint (in fact it seems Mint is the grandson of Debian, since Mint is based on Ubuntu). The difference of distribution if I use package manager, is that package names are different although the packages are of the same functions.
Arch Linux: xorg-server, xorg-server-utils, xorg-xinit, xf86-input-mouse, xf86-input-keyboard.
Debian Linux: xserver-xorg-core, x11-xserver-utils, xinit, xserver-xorg-input-mouse, xserver-xorg-input-kbd.
Knowing these packages name helps making a customized (installed what I need and not everything provided by distribution) system easier.
There is no /etc/rc.conf, in fact loading modules (drivers) is easier than Arch Linux, udev did a great job in identifying and load the respective modules in Debian.
There is however /etc/inittab, the run level is actually highly configurablem in Debian:
runlevel 0 is still halt
runlevel 1 is still single user mode
runlevel 2-5 is multiuser mode
runlevel 6 is still reboot.
In Arch Linux, runlevel 3 is the console and runlevel 5 is the X11.
The first thing before doing any installation for Debian, update with apt-get then apt-get install sudo.
If /etc/sudoers is not found, sudo will create one which suits well for the job, a group sudo is create and a default %sudo ALL=(ALL) ALL.
