Preparation
When the login screen comes around you may enter in your system with the root user, “toor” is the default password with SLAX unless you change it, /etc/issue is exposure a lot of helpful information for newbies as well (root/toor, xconf, startx, …)Now in less than 5 minutes you’ll be able to make your new virtual machine, let’s make a simple environment:
root@slax:~# mkdir target target/image target/iso root@slax:~# cd target/image/Now it’s time to copy the contents of your build machine into your target host space:
root@slax:~/target/image# cp /mnt/sda1/boot . -R root@slax:~/target/image# cp /mnt/sda1/slax . -R root@slax:~/target/image# ls -la total 16 drwxr-xr-x 4 root root 4096 May 30 17:35 ./ drwxr-xr-x 3 root root 4096 May 30 17:33 ../ dr-xr-xr-x 6 root root 4096 May 30 17:35 boot/ dr-xr-xr-x 7 root root 4096 May 30 17:35 slax/Everywhere /mnt/sda1/ is my root partition, if you’ve followed my previous article you may have the same device name, expecially if you’ve installed it in a virtual host (I’m using VMWare), if you’re not under /mnt/sda1 you may learn your root partition name, it ain’t that hard:
root@slax:~/target/image# df Filesystem 1K-blocks Used Available Use% Mounted on aufs 7115576 631668 6122448 10% / tmpfs 255440 0 255440 0% /dev/shm /dev/sda1 7115576 631668 6122448 10% /mnt/sda1Now in your target directory you’ve the essential organize of your new target device
root@slax:~/target/image# ls -la total 16 drwxr-xr-x 4 root root 4096 May 30 17:35 ./ drwxr-xr-x 3 root root 4096 May 30 17:33 ../ dr-xr-xr-x 6 root root 4096 May 30 17:35 boot/ dr-xr-xr-x 7 root root 4096 May 30 17:35 slax/This is just what you need to make your new target system
Making a target ISO
to make a target ISO with an exact copy of your system you only need to use a equipped made script file located under target/image/slax directory, invocation is straightforward:root@slax:~/target# ./image/slax/make_iso.sh iso/mycoolimage.iso 2.01.01a53 (i686-pc-linux-gnu) Scanning ../.

root@slax:~/target# ls -la iso/ total 205084 drwxr-xr-x 2 root root 4096 May 30 17:44 ./ drwxr-xr-x 4 root root 4096 May 30 17:36 ../ -rw-r--r-- 1 root root 209784832 May 30 17:44 mycoolimage.isoyou may make a small script if you want to automate the whole process:
#!/bin/bash # This script builds an ISO file from the image made BASEPATH=/mnt/sda1/target REMOTEHOST=192.168.84.1 mkdir -p $BASEPATH/iso $BASEPATH/image/slax/make_iso.sh $BASEPATH/iso/image.iso scp $BASEPATH/iso/image.iso ben@$REMOTEHOST:/iso/image.isop { margin-bottom: 0.08in; }
To make my own tests I’ve two virtual machines, one it’s called “Slax Build Machine”, one it’s called “Slax Test Machine”. “Slax Build Machine” is the machine we’re now using and the same machine we’ve built in the previous chapter. “Slax Test Machine” it’s an unfilled VMWare virtual machine, no hard drives, just a virtual cdrom device pointing to an ISO file located on the real host (in the directory /tmp/image.iso). When I’d like to make some tests I just need to make an ISO file (in the build machine with the previous script). The script copies the .ISO image in the physical host with the creation, then I start the Test Machine when needed, I don’t need to waste CDs or reinstall/configure the virtual machine each time, it’s really simple
In this chapter we’ve just made an like peas in a pod copy of our build machine, in the next chapter we’ll make to order the test machine, we’ll start with a bare bone system and we’ll add modules/functionalities later on
I guess this phase is really simple but it’s vital to be with you it well, from the next phase you’ll be with you why customizing and building a slax machine is really simple and powerful
