Skype is the next phenomenon from the people who brought you KaZaA. Just like KaZaA, Skype uses P2P (peer-to-peer) technology to connect you to other users – not to share files this time, but to talk for free with your friends.
The technology is extremely advanced - but super simple to use... You’ll be making perfect quality free phone calls to your friends in no time! Just tell them to get Skype as well, if they don’t already have it.

加了 -j, 預設多了 4MB 的日誌

/dev/hda1 125056 146 124910 1% /mnt
-J size=1 是最小, 日誌最小為 1024 blocks, 即 -J size=1
結論: 要空間佔最小, mkfs 後空間最大(但是 inode 較少), 日誌最小用
mke2fs -b 1024 -i 8192 -J size=1
Gallery is now internationalized, and can be displayed in over 20 languages! In addition, we've completely overhauled the documentation and made it more accessible and more informative. Other changes include ownership of individual album items, not just of albums, and a slew of minor improvements and bugfixes.

欲製作的 system root directory 在 /systemroot
size 大小為 32mb 的 initrd
CF 在 /dev/hdc, 已格式化, 只有一個 partition /dev/hdc1
boot loader 使用 grub
Step 1: 製作 initrd loop device
dd if=/dev/zero of=initrd bs=1024k count=32
mke2fs -F -m0 -i 2048 initrd
mount -o loop initrd /mnt
Step 2: 複製系統至 initrd, 不含 kernel
cp -a /systemroot/* /mnt
umount /mnt
Step 3: 壓縮 initrd, 產生 initrd.gz
gzip -9 initrd
Step 4: 將 kernel 及 initrd.gz 複製到目標(CF, DOM...etc.)
mount /dev/hdc1 /mnt
cp kernel initrd.gz /mnt
Step 5: 安裝 boot loader
cp -a /boot/grub /mnt
printf "root (hd0,0)\nsetup (hd1)\nquit\n" | grub --no-floppy --batch
Step 6: 設定開機設定(menu.lst)
編輯 /mnt/grub/menu.lst 內容如下
timeout 0
default 0
title linux
root (hd0,0)
kernel /kernel ramdisk_size=32768 root=/dev/ram0 quite
initrd /initrd.gz
