How to start automatically a script after that the knoppix user is logged on.

Hello to everyone,

I'm trying to make a customized version of KNOPPIX 6.2 that should run totally in RAM.
The customizations I need to do are very few :

1) automount in write mode the first two NTFS/FAT32 partitions of the first hard disk
2) mount the CD/ROM after the default user (knoppix) or (root ?) is logged on
3) start automatically a session of DOSEMU after that the knoppix user is logged on

This is what I did while I was in chroot :

apt-get install dosemu

cd /mnt
mkdir cdrom
mkdir hda1
mkdir hda2
mkdir sda1
mkdir sda2

cd /home/knoppix/.dosemu/drives/c

nano autoexec.bat

lredir e: linux\fs/mnt/cdrom c
lredir f: linux\fs/mnt/hda1
lredir g: linux\fs/mnt/hda2
lredir h: linux\fs/mnt/sda1
lredir i: linux\fs/mnt/sda2

nano /home/knoppix/.bash_profile

#!/bin/sh
clear
read -p "Insert your Windows installation disk and press a key to continue" disco
sudo mount -t auto /dev/cdrom /mnt/cdrom
dosemu

mv /etc/skel /etc/skel-old
mv /home/knoppix /etc/skel
chown root:root -R /etc/skel

cp -Rp /etc/skel /home/knoppix
chown knoppix:knoppix -R /home/knoppix

When Knoppix starts the script I put in /home/knoppix/.bash_profile is not executed. Why ?
The folder /home/knoppix is empty. Instead,I have everything on /etc/skel/,like the .dosemu folder and the .bash_profile script. I would like that it is placed on /home/knoppix and that it is executed when the knoppix starts. Thanks.

It would help me if you'd expand this more.

An obvious question is: have you considered the 'toram' cheatcode?

Yes,I will use this option,but the problem now is that I don't know how to start automatically the script inside .bash_profile when the Knoppix has been loaded in Ram

You can start any program at the end of the boot process
via a script in /etc/rc.local.

Does that help?

/etc/rc.local

SERVICES="cups"

for i in $SERVICES; do
[ -x /etc/init.d/"$i" ] && /etc/init.d/"$i" start >/dev/null 2>&1
done

/etc/skel/script.sh

exit o


/etc/skel/script.sh

#!/bin/sh
clear
read -p "Insert your Windows installation disk and press a key to continue" disco
sudo mount -t auto /dev/cdrom /mnt/cdrom
dosemu

is this right ?

I don't know what you want to achieve.

I wonder if you meant exit 0 as in exit zero, not o.

Try it and find out.

For openers, /etc/rc.local is directory.
Define your shell scripts appropriately and save them there.
They get executed in the order presented in the directory.

You have here a melange of things (in post #5)
that would surprise me if it did anything useful as it stands.
Perhaps 'try it and find out' is a bit premature.

In regards to I/O re-direction, of any sort, I can't help you.

I think you will get more help from some quarter if you
define in words, more than a short sentence just what you hope to achieve.

post #7 got past me with the darn ten minute edit rule

wrong

/etc/rc.local is an executable script itself.
your can reference other scripts in it.

Best to keep things small and separate.

Remainder of my post #7 about right, I think.

I copied script.sh inside /etc/

#!/bin/sh

clear
read -p "Insert your Windows installation disk and press a key to continue" disco
sudo mount -t auto /dev/cdrom /mnt/cdrom
dosemu

I call it inside the /etc/rc.local file :

rc.local

....
/etc/script.sh

I made it executable,with chmod +x script.sh

and at the end I re-booted Knoppix with runlevel 2,but when it has finished to be loaded in memory,the script.sh is not started.

Since you made it executable it is better to remove the .sh extension and place your script in /usr/sbin, then make a line in /etc/rc.local
Make sure again it is chmod 755

rc.local is the last script executed at every runlevel 2,3,4 and 5

Where did you look for the output of /etc/rc.local ? If you read the file /etc/init.d/knoppix-autoconfig you will find the command line where /etc/rc.local is executed on virtual terminal #12. I think you have to switch over to vt #12. But if there are additional messages on this vt coming from services already started or the kernel it might be difficult to identify rc.local's output. Thus, I think, altering the vt from #12 to #11 could help. In addition I would switch over to vt #11 before the read command is executed. The old command line in /etc/init.d/knoppix-autoconfig is

Code:

---

[ -x /etc/rc.local ] && /usr/bin/openvt -c 12 -f -- /etc/rc.local

---

The new command line could be

Code:

---

[ -x /etc/rc.local ] && /usr/bin/openvt -c 11 -w -b -f -s -- /etc/rc.local

It takes some time to display the message "Insert the Windows installation disk" ,but it works. Thanks.
