mksquashfs

まあ 本質では無いが にゃんたろうが 適当な 確認をしておきます。

log を 残す場所を作成

# df | sed 2,5d | sed 3d
Filesystem     1K-blocks     Used Available Use% Mounted on
/dev/sda9      133136404 12409820 114016900  10% /root/work/sda9
# ls
bin/    dev/      home/     loop/        misc/  opt/      root/  srv/  usr/
boot/   etc/      install/  lost+found/  mnt/   proc/     run/   sys/  var/
cdrom/  fastboot  lib/      media/       net/   put_old/  sbin/  tmp/
# cd home/fdopstm/
# mkdir 004_log-ZANTEI /*   まあ log を 残す場所を作成しておきます。  */
# chown fdopstm.users 004_log-ZANTEI/
# cd ../../

これで rootimg.squash の 準備が 完了しました ので 作成します。
