TinyCore Linux – Remaster

Version : 4.5.5

Preparation


a. Download TinyCore[link1] Linux

wget -c http://distro.ibiblio.org/tinycorelinux/4.x/x86/release/TinyCore-current.iso


b. Create local folders & mount TinyCore

mkdir -pv tinymount tinylocal tinycde
 
mount -o loop TinyCore-current.iso tinymount


c. Copy & extract Core cpio image

cp tinymount/boot/core.gz tinylocal/
 
cd tinylocal
 
gunzip core.gz
 
cpio -i < core
 
rm core


d. At this point you can chroot the new environment for testing it:

chroot ./ /bin/sh


Be aware that you need to mount sys,dev & proc with bind option to work properly.

Install packages


a. Download your packages (and their dependencies) from:

http://distro.ibiblio.org/tinycorelinux/4.x/x86/tcz/

cd ../tinycde
wget packages ...


b. Install packages to your tiny core environment

you 'll need squashfs-tools[link2]

cd ../tinylocal
 
forin `ls -1 ../tinycde/*tcz` ; do unsquashfs -f -d . $i ; done
forin `ls -1 ../tinymount/cde/optional/*tcz` ; do unsquashfs -f -d . $i ; done

Customize your tinycore


Use chroot and customize your new tinycore environment.

If you want your tc user to auto-whatever you need-start something (like X):

a.
vim etc/skel/.profile


(after clear command)

b.
forin `ls -1 /usr/local/tce.installed`; do sudo /usr/local/tce.installed/$i  ; done

Archive your tinycore environment


first exit from chroot env
You 'll need AdvanceCOMP[link3]

a.

find | cpio -o -H newc > ../core
cd ..
gzip core
advdef -z4 core.gz

PXE BOOT


If you need to pxe boot your new tinycore, you are done !

below is the configuration to default (pxelinux.cfg/default):

LABEL TinyCoreLinux
	MENU LABEL TinyCoreLinux
	LINUX vmlinuz
	INITRD core.gz


The vmlinuz image is here: tinymount/boot/vmlinuz

ISO 


If you need an iso

a. Create the file structure

cd ../
mkdir -pv tinyiso
cd tinyiso
cp -rav ../tinymount/boot/* .
mv ../core.gz core.gz


b. Edit isolinux.cfg

# vi isolinux/isolinux.cfg


DEFAULT menu.c32
PROMPT 0
TIMEOUT 10

MENU TITLE TinyCore
MENU MARGIN 6
MENU VSHIFT 1
MENU ROWS 13

LABEL TinyCore
MENU DEFAULT
MENU LABEL TinyCore 
KERNEL /vmlinuz
APPEND initrd=/core.gz


c. Create the iso file:

mkisofs -l -J -R -V TinyCore -no-emul-boot -boot-load-size 4 -boot-info-table -b isolinux/isolinux.bin -c isolinux/boot.cat -o ../my.iso .
