Hello again,

I've also hacked together a script that creates an iso-image which eases up the installation process in two ways.

Either your installing TCL in an NTFS partition: for this case the ISO an initramfs with ntfs-3g integrated. GRUB4DOS is used as the bootloader of the CD and can also be used for booting TCL from the Windows bootloader just by copying it to harddisk, if you're using Windows XP. If you're using Windows Vista or later, all files needed for integration in the Windows bootloader are also integrated, but you'll need to do a bit more than just copying.

If you're installing TCL in a native partition also everything you need is included and you can setup your new system in just four steps:
- partition harddisk
- format Linux partition
- copy the whole contents of the CD to the newly created partition
- run bootlace.com (yes, even though it's a .com it also runs on Linux) to write the bootloader loading GRUB4DOS

That's all. No more downloading of grub-0.97-splash, no need to edit boot/grub/menu.lst.

A PXE loader is also included in case you want to boot via network but your machine lacks the support.

At the time of writing the script looks like this:
Code: [Select]

TCMIRROR="http://distro.ibiblio.org/pub/linux/distributions/tinycorelinux/3.x"

squashfs-tools-4.0.tcz is also needed, but why should wget from busybox not work?

This script is also intended to run on any Linux, not just Tiny Core Linux. In fact it was developed and tested on an Ubuntu machine and is also running on a Debian GNU/Linux, which depends on a self-compiled squashfs-tools-4.0, since the current Debian only contains squashfs-tools-3.3.

With busybox wget, for one the --referer option is not available.

And mkisofs is part of mkisofs-tools.tcz
