Customizing SLAX - part 1

I am currently learning about how to produce live Linux CD system. Yes I know, this may be very old and very simple for you. But I haven't sharpen my Linux skills since a year and half. This will be a good practise.

I chose SLAX (www.slax.org) because the manual said it was developed to be hacked. So here I am customizing SLAX.

In the first part of the customization, I will remove a SLAX module and add several modules (antivirus, wiping utilities, hash utilities). That's look very easy. :D

Here are the steps I took to do my objectives :

- Download the SLAX base from http://slax.linux-live.org

- Download the required modules from the above site. The modules I downloaded are :

- ClamAV 0.88.4
- md5deep_sha1deep
- wipe

- After finish download SLAX base and its module, I copy the whole SLAX base to my working directory :

# mount -t iso9660 -o loop slax-5.18.iso /media/images
# mkdir /home/tedi/projects/slax
# cp -R /media/images /home/tedi/projects/slax
# chown -R tedi.users /home/tedi/projects/slax/*

- Then I change to the SLAX directory :

$ cd projects/slax

- Remove kde_office.mo module

$ rm base/08_kde_office.mo

- Move three modules to modules/ directory :

$ mv ~/*.mo modules/

Here is the content of the modules/ directory :

-rw-r--r-- 1 tedi users 6758400 2006-12-06 12:11 ClamAV_0_88_4.mo
-rw-r--r-- 1 tedi users 118784 2006-12-06 11:37 md5deep_sha1deep_etc_1_12.mo
-rw-r--r-- 1 tedi users 40960 2006-12-06 11:37 wipe_0_20_1-1.mo

- After that I create a new SLAX iso :

$ ./make_iso.sh ../slax-new.iso

- To test the new iso, I use "qemu" :

$ cd
$ qemu -cdrom slax-new.iso -boot d

- When the new SLAX started, I login and check whether the new modules are there, and yes they are.

- Time to celebrate.... :d

In the next installment, I will try to modify existing modules and add several more application to SLAX.

Until next time
