System.map “/boot”
In order to use the new kernel image you have just installed, you
will need to reboot the machine. First, however, you will need to
either make a bootable floppy diskette, re-run LILO, or have GRUB
installed.

Checking for ELILO…No

GRUB is installed. To automatically switch to new kernels, point your
default entry in menu.lst to /boot/vmlinuz-2.6.30.4

====================
GRUB menu configuration file menu.lst should be update.

using root account do following.

#make mrproper #check kernel .o and .config files

next configuration kernel. there are three kinds of configuration UI.

#make config #Text UI

#make menuconfig #Text graph UI

#make xconfig

before using menuconfig mode, ncurses should be installed. 

#apt-get install libncurses*

and before using xconfig mode, following package should be installed. 

#apt-get install libqt3-headers libqt3-mt-dev

after all configuration work done. using make command to compile kernel.

pacman using wget for download task. but wget is not for multiple thread download. if using “aria2″, the download speed can sharply increase.

firstly, install aria2 by:

$pacman -Sy

$pacman -S aria2

then, edit /etc/pacman.conf, add a line:

XferCommand = /usr/bin/aria2c -s 2 -m 2 -d / -o %o %u

ok, try pacman again, you can see big change for download speed.
