일단 grub2

/etc/default/grub

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=4
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 text"
GRUB_CMDLINE_LINUX=""

가능하면 grub2를 제거하자....ㅋ

/etc/nsswitch.conf

hosts: files mdns4_minimal [NOTFOUND=return] dns

ssh 접속을 빠르게 해줌

boot parameter에서

console=tty0 text

위를 추가하면 gdm 안 뜬다.

network-manager 제거

apt-get remove network-manager
