建置root filesystem

使用busybox建置root filesystem

通常在/etc/inittab檔:
::sysinit:/etc/init.d/rcS

那所有的mount mknod動作皆可直接寫在/etc/rcS 如圖下:
echo
echo Welcome to MontaVista Linux Preview Kit
echo
echo Starting system...

# First mount /proc!
echo -n "mounting /proc: "
mount -n /proc /proc -t proc
echo "done."

# Make sure / is ro (this is fixed, now it is rw)
echo -n "Mounting '/' read-only: "
mount -n -o remount,rw /
echo "done."

# Bring up loopback
echo -n "brining up loopback interface: "
ifconfig lo 127.0.0.1 up
echo "done."
touch /tmp/utmp
touch /tmp/wtmp
touch /tmp/lastlog
touch /tmp/messages
touch /tmp/thttpd.log

# Start syslogd/klogd
echo -n "Starting syslogd: "
syslogd
echo "done."
echo -n "Starting klogd: "
klogd
echo "done."

# Start inetd
echo -n "Starting inetd: "
/usr/sbin/inetd
echo "done."

# Start thttpd
echo -n "Starting thttpd: "
/usr/sbin/thttpd -C /etc/thttpd/thttpd.conf -i /var/run/thttpd.pid -c "/cgi-bin/*"
sleep 1
echo "done."

echo System started.

# QVGA dev nod
echo QVGA mknod created
mknod /dev/fb0                  c 29 0
mknod /dev/pwl                  c 46 0
mknod /dev/keypad               c 42 0
mknod /dev/touchscreen  c 43 0
mknod /dev/ledDevice    c 10 20

# // / usb dev nod
mknod /dev/sda1 b 8 1

# // / dsp audio dev nod
mknod /dev/mixer c 14 0
mknod /dev/dsp c 14 3

這些是怎麼跟對應的位置做連結?還是在這邊寫好就行了?

怎麼跟對應的位置做連結?
mount 后面跟的有路径呀。

Kernel panic-not syncing: No init found. Try passing init= option to kernel
這是我啟動後出現的情況

这个文件系统是你自己做的？

嗯啊，我想自己建置一個試看看

我是不知道為什麼出現:NO init found

照理說 /etc/inittab寫好 裡面就有init的路徑

已解決 THX!!!
