Debian下pietty+screen

最近在vm下試debian與centos，發現只要是centos開screen，pietty上面會有一些不一定的文字...

但debian就沒有...原來是 PROMPT_COMMAND 與 /etc/screenrc  的問題

Debian 7.1下改grub2的開機桌布

上課打混用...


0.先裝套件
#apt-get  install grub2-splashimages
#ls  -l /usr/share/images/grub

1.修改設定
#vi /etc/default/grub

加入
GRUB_BACKGROUND="/usr/share/images/grub/Lake_mapourika_NZ.tga"
要確定下面這行有被註解
GRUB_TERMINAL=console

2.這個順便修改一下，加入紅色那行，約在132之後
# vi /etc/grub.d/00_header
if loadfont `make_system_path_relative_to_its_root "${GRUB_FONT_PATH}"` ; then
  set gfxmode=${GRUB_GFXMODE}
  set gfxpayload=keep
  load_video
  insmod gfxterm

3.更該配色...(不過好像改不太出來...)
#vi /etc/grub.d/05_debian_theme
set menu_color_normal=green/yellow
set menu_color_highlight=yellow/red


4.更新grub2，再重新開機...至少圖片賞心悅目多了...
#update-grub

安裝sysstat失敗...update-rc.d: error: insserv rejected the script header

錯誤訊息一堆...想移也移不掉...

insserv: Starting noip2 depends on minissdpd and therefore on system facility `$all' which can not be true!
insserv: Max recursions depth 99 reached
insserv:  loop involving service noip2 at depth 1
insserv: exiting now without changing boot order!
update-rc.d: error: insserv rejected the script header
dpkg: error processing sysstat (--purge):
 subprocess installed post-removal script returned error exit status 1
Errors were encountered while processing:
 sysstat
E: Sub-process /usr/bin/dpkg returned an error code (1)

查了一下google
原來是少了header...
#vi /etc/init.d/noip2



加入
### BEGIN INIT INFO
# Provides:          noip2
# Required-Start:    $syslog
# Required-Stop:     $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: noip2 service
# Description:       noip2 service
### END INIT INFO

之後移除再安裝就不會有問題啦...
