nash initrd can be changed bash?

[Hyung-Koo Kang]

Hi~everybody in this mailing-list.

i got some pending problem.

i'd like to convert nash shell in initrd to bash.

but, some commands did not exist in the bash shell.

as you know, there are three comands. those are mkrootdev, switchroot
and setquiet.

1>mkrootdev
2>switchroot
3>setquiet

what are these three? could somebody explain?

if you know these can be changed some commands in bash,
please let me know that.

i already did googling. but i couldn't find that.

following shows init in nash initrd.
=================================================
#!/bin/nash
mount -t proc /proc /proc
setquiet
echo Mounted /proc filesystem
echo Mounting sysfs
mount -t sysfs none /sys
echo Creating /dev
mount -o mode=0755 -t tmpfs none /dev
mknod /dev/console c 5 1
mknod /dev/null c 1 3
mknod /dev/zero c 1 5
mkdir /dev/pts
mkdir /dev/shm
echo Starting udev
/sbin/udevstart
echo -n "/sbin/hotplug" > /proc/sys/kernel/hotplug

echo Mounting root filesystem
mount -o defaults --ro -t ext3 /dev/root /sysroot
mount -t tmpfs --bind /dev /sysroot/dev
echo Switching to new root
switchroot /sysroot
umount /initrd/dev
