default tce directory in iso ?
« on: January 19, 2010, 03:47:41 PM »
Hi,
This might be a dumb question. Can you have the tc's iso have a default tce directory like slax's modules directory ? Any reason that this is not practical ? (grub2 support boot from iso, custom iso, don't have to download all the time when boot from iso,....)

Thanks

inside TC.iso

/boot
/tce      <--- I can then use "iso Master" to add extensions into this directory then boot up will load these extensions from iso

If you create an Ext3 partition on the hard drive, then create a tce directory in it, put extensions in the tce directory, and boot from the cd, it will find the tce directory and load programs. Everything should work normally. Use version 2.7.

When you have done that, there is not much more to do for a full installation.


I have not tried this booting from an iso image on the hard drive. It is likely to work. If you try it, post your results.

With the latest version 2.8rc3, the default directory for extensions is /tce/optional. This is likely to be the case when 2.8 final comes out. But it has not been released yet, so wait and see.


You can also make a cd with programs.

Guy,
Thanks for the info.
grub2 does boot from HDD with tce extensions. Waiting for 2.8 final to build multi boot USB flash drive with just iso files only. :)

..boot from the iso file? If so, what grub2 setup did you use?

Hi Juanito,
Do you mean what i put inside the grub.cfg ?
==================
menuentry "TinyCore 2.7 iso"  {
   set iso="/iso/tinycore_2.7.iso"
   search --set -f $iso
   loopback iso (hd0,7)$iso
   linux (iso)/boot/bzImage quiet lang=en kmap=us noutc max_loop=255 tce=hdc7/tinycore/tce
   initrd (iso)/boot/tinycore.gz
}
==================

If you remaster an ISO and put extensions in /opt/tce/optional with a link from /opt/tce/, then 2.8rc3 will load those extensions during the boot process.

For example, I remastered microcore_2.8rc3 to add the Dropbear ssh server and got the following structure:

Code: [Select]
$ ls -lR /opt/tce

/opt/tce:
lrwxrwxrwx    1 root     staff          21 Jan 19 22:20 dropbear.tcz -> optional/dropbear.tcz
drwxr-sr-x    2 root     staff         240 Jan 19 22:20 optional

/opt/tce/optional:
-rw-r--r--    1 root     root        94208 Jan 17 20:39 dropbear.tcz
-rw-r--r--    1 root     root           47 Jan 17 20:39 dropbear.tcz.md5.txt

Dropbear is then available whenever I boot the remastered ISO.

That's exactly what I meant, thanks.

Looks like we need a grub2 extension  :P

hi vitex,
There's no /opt/tce directory inside the mc.iso, so i just create one inside the iso ?

You need to create /opt/tce inside the file system within the file /boot/microcore.gz on the ISO.  See the wiki for detail about how to unpack and repack microcore.gz.

You can use tce= if you need persistent storage for extensions that you install during execution, but you do not need tce= to boot and use the remastered ISO.  (If I want to add an extension, I just remaster the ISO, which typically takes only a minute or so.)

For example, I typically run MC in a qemu virtual machine and execute a version of MC (mcssh.iso) that is remastered to have the Dropbear ssh server with my public key installed:

Code: [Select]
qemu -m 128 -cdrom /tmp/mcssh.iso -redir tcp:22222::22 -boot d
That is the equivalent of booting the ISO on a bare machine.  I use scp and rsync over ssh to save and restore state of the (virtual) MC machine.

You don't need it.

If you have a tce directory on the hard drive, and boot from the cd, Tiny Core will find it.

Thanks Guy. Would like to have the extensions inside the iso instead. Waite for TC2.8 :). I'll try putting tce inside 2.7's boot directory /boot/tce then remove the tce= from the boot menu see if that works on current version (since you said it'll search for the directory itself).

Not working. I think after loading the kernel and initrd the iso directory structure is invisible from the search (which make sense).

Don't put it in /boot/tce, just /tce, and it should work.

This works if booting from the cd. I havn't tried other methods.
