 Read tinycore/readme.txt to build a modified Tiny Core Linux
 Read qemu.txt for testing the image and update it

 To create the bootable usb key use this command:

	LINUX: zcat tcl-usb.disk.gz > /dev/sd${letter}

	WINDOWS: rufus select tcl-usb.disk.gz and write

 USB firt partition label: T1NYC0R3 (but you can change it in rcS)

 Make any changes you like and be sure to update these files

	rootfs.gz tccuston.tgz sshdconfig.tgz

 To download tinycore components use:

	tinycore/provides/tcgetdistro.sh

 HOW TO BUILD THE IMAGE FROM SKELETON

 To create the new image: ./make.sh image
 After, to create the 8GB image: ./make.sh image 8GB
 To compress the new images: ./make.sh close 

 HOW TO UPDATE THE IMAGE WITH QEMU

 To update the usb image do: ./make.sh all
 After, to recreate the 8GB image: ./make.sh all 8GB

 These procedure requires that qemu-system-i386 is installed

 To update a running machine: ./make.sh ssh-copy ip.addr


 ############ HOW TO MODIFY THE IMAGE ############
 
 zcat tcl-usb.disk.gz >tcl-usb.disk
 sudo losetup --partscan /dev/loop8 tcl-usb.disk
 mkdir -p tcldisk
 sudo mount /dev/loop8p1 tcldisk

 sudo dd if=/dev/zero of=tcldisk/zero 
 sync
 sudo rm -f tcldisk/zero
 sudo umount tcldisk
 sudo losetup -D /dev/loop8
 gzip -9c tcl-usb.disk >tcl-usb.disk.gz
