(If we want English, just change above line by
Language="en_US.UTF-8")

Next, check the fc-list the name of the Japanese font to use.
$ fc-list | grep Takao Takao P??,TakaoPMincho:style=Regular Takao????,TakaoGothic:style=Regular Takao P????,TakaoPGothic:style=Regular TakaoEx????,TakaoExGothic:style=Regular TakaoEx??,TakaoExMincho:style=Regular Takao??,TakaoMincho:style=Regular
Add the following lines to a file takao.map (create new if not exist) under the directory /etc/texmf/vfontmap.d/

[root@tube40 ~]# emacs /etc/ntp.confThe /etc/ntp.conf file is the main configuration file for Linux NTP in which we place the IP addresses of the servers we want to use. Here we only use one server:
server ntp.tohoku.ac.jp # A stratum 1 server at tohoku.ac.jp #server ntp.redhat.com # A stratum 2 server at redhat.comWe have to restart the NTP process every time we make a change to the configuration file for the changes to take effect on the running process.

Since we do not know what is the process of mount the file. we can not change mtab to snapshot. For a moment, we force mount /home1 and /rsaito on /tmp/home1, /tmp/rsaito
/etc/rc5.d/S28autofs stop mkdir /tmp/home1 mkdir /tmp/rsaito mount -n 192.168.2.100:/home1 /tmp/home1 mount -n 192.168.2.100:/rsaito /tmp/rsaito df

This is due to mounting problem again (mount NFS). After checking mount status, it is found that a network harddisk was not unmounted nicely before turning off.
# mount
# umount -f /mnt/backup
# sync # sync # sync
comment out one line in /etc/auto.misc # home1 172.17.4.134:/home1-old
./S28autofs forcerestart
I also delete in /etc/exports
the requests from 172.17.4.184 (nuguraha) 172.17.4.188 (mahabubu) and 172.17.4.127 (furu).
exportfs -a
we also need to restart nfs /etc/rc5.d/S60nfs restart
Then many selection of OS appears. Select one of OS, and press E. Then select kernel and press E again. Then you can edit the command for starting kernel and add "single" in the last of the command. Finally select "b" for booting and single user mode appears. Make /etc/passwd files and exit and runlevel 5 is recovers.
Even if we used NIS, we should not delete /etc/passwd /etc/group and /etc/shadow.
