I found a really simple way to create a 10.4.8 live DVD with 8.8.1 semthex kernel (ty).
but see yourself, here is a movie captured in vmware.

http://www.mediafire.com/?endnnmdydnn

I will write down what I did exactly and post a detailed "how to" within the next days.
I need to create a Extensions.mkext with correct timestamp first.

ps.: we also have a full 10.4.8 install DVD now (10.4.4 based DVDs are gone) ^_^

greets,
modbin

And AMD friendly too... that's great. Looking forward to it.

Btw, would customization be straightforward, say for not loading dashboard or other dock items? Or replacing Safari with Firefox?

Thanks.

Well this is most interesting, and I look forwards to reading the How-To. I assume this started out with an original 10.4.8 install DVD, I didn't know there was such a beast. fun fun fun :)

It would really be awesome if the 10.4.8 Live DVD was like the Ubuntu Live CD in that it would give you the option to install by clicking a button. ;)

In the past, when buying a computer, I would bring in a Linux live cd with me to a store in order to see how compatable the hardware was with whatever flavour of Linux I wanted to try. I admit, I can be a lazy sod but I would rather be spending my time running a working OS than to sit for a week plugging away at it til I got it configured my way (or at least til the next build was out and start all over).

Now, with the live osx cd, it will great fun to try it out in a store and test it out on a computer/laptop that I have my eyes on. Even more fun is to watch the sales staff watch as the OS boots up. It is the simple things in life that appeal to me.

I already did this with my 10.4.4 live /install DVD and it was big fun :happymac:

back to topic:

Back in town for the weekend I had some time to write down the "how to" for you.
I`m not shure if I replaced the keychain folder in
/private/etc/Ramdisk/contents/private/var/root/Library/ ,test it.

How to create a 10.4.8 live DVD:

-follow semthex`s guide to install 10.4.8 onto a seperate partition,
boot 10.4.8 enable root user and make it autologin
install your favorite apps and setup your preferences and so on.
open keychain access and delete your keychains

-reboot and check if everything is working (all permissions correct?)!

-reboot to your first OS X install (not the 10.4.8 you just created!)

-open teminal and mount a jas or myzar osx install iso you have laying around
"hdiutil attach dragyourimagehere -readwrite" without quotes
save the automount folder for later use
-delete everything inside the image we just need the boot sector
finder won`t allow you to delete the .trashes and desktop db/df files, it`s ok.

-open Disk Utility ,select the empty iso and click restore
as source drag in the new 10.4.8 hd install you created
as destination the iso
click restore (don`t check Erase Destination)

-wait (time for some hot coffee/girlfriend)

-done? fun? ok save the /private/var/root/Library/Preferences folder for later use
delete the private folder and replace it with my patched one.

cut the following folders
/Library/Caches
/Library/Logs
and paste them into
/private/etc/Ramdisk/contents/Library/

now cut
/System/Library/Caches
and paste it into
/private/etc/Ramdisk/contents/System/Library/
now
/Users
and paste into
/private/etc/Ramdisk/contents/

now paste in the following symlinks
/Library/Caches
/Library/Logs
/System/Library/Caches
/Users

paste in back the automount folder
paste in the RamDisk command into /usr/bin/
paste in /System/Installation/CDIS

delete the /System/Library/Extensions.mkext

add the kernel flags -v -legacy in /Library/Preferences/SystemConfiguration/com.apple.boot.plist
-v is not needed if you specify a fixed ramdisk size in /private/etc/rc

Attention! changing the kernel afterwards will not work because of the kernelcache

please test if this works for you and post your results here, ty
It`s pure fun to have an OS X live DVD.

ps.:for a install dvd you have to repack the EssentialSystemSoftwareGroup.
open osinstall.mpkg with pacifist and take a look at it.

greets,
modbin :hysterical:

edit:the zip should be ok now

Haha. Nice SaberSHO.

modbin - great guide! I'll be testing it out later on my USB HD, i'd love to have a pre-made 10.4.8 image (with semthex beta 3 kernel - so I can boot in VMWare with both cores ;))

Nice work :)

Edit: Didn't like me adding a USB HD in VMWare... looks like i'll have to wait til I get some DVD-R's.

Just finished replacing files and am burning now I will report back on what happens.

EDIT: It boots but ramdisk isn't working...almost there!

P.S. I made a channel on irc #live.dvd to talk about the live dvd and the progress and errors and whatnot so join if you need help or suggestions.

paste in the files from your osx installation into your mounted dvd
btw,
tip : you can use windows+shift+g to get to folders you can't find in the finder
and to get the the hidden folders on the dvd use windows+shift+g and type /Volumes/Mac OS X Install Disc x86/ <----- path e.g /usr/libexec

Thank you modbin for the guide.

I have a few questions too, hoping they're not too noobish:
  • After mounting the myz/jas iso, the guide says "save the automount folder for later use". But I see no such folder in either iso's. (I've unhidden files/folders with Onyx).
  • Near the end of the guide it says: "paste in /System/Installation/CDIS"; I assume this was saved from the above iso, right?
  • The dvdroot.zip also contains two folders, "ramdisk" and "ramdisk.inkernel", each containing a symlink. The guide doesn't refer to them; where should we put them? Do we put both folders in the root of the dvd?
  • /private/etc/RamDisk/contents/Library/ contains a folder "Application Support/copy and paste here". I assume it is the /private/var/root/Library/Preferences folder that was saved after the Restore, right?

1: dont worry about the automount after restoring and booting it showed up.
2: Installation is for if you need install and yes from previous.
3: Ramdisk and Ramdisk.inkernel both go in / (root) of the iso.
4: It is actually the one from the previous install that you restore onto the iso.

I'm not sure of the folder on #4 but i will check and change it.

Ok, thanks for the clarifications.

As for #4, ok, I see a bit better now. We should then just copy to the RamDisk/contents/Library/ the /Library/Application Support that is already in the Live image.

Now to know of what use is the saved "/private/var/root/Library/Preferences"; probably to place in same place as above, but will wait for confirmation.

Also, what minimum is suggested for the ramdisk?
