Is this possible? I would like to install Gentoo on my Ipod and use it as an external HDD with my new ibook.

My ipod is currently fat32 formatted since it was bought for me before the ibook, will this make a difference - can I still boot from it?

I'm a real novice when it comes to apple hardware, I havn't even figured how to actually boot from an external device yet.... Tried the Option key on boot which loaded up and show an icon for my mac hdd but the ipod hdd was not displayed.... Do I have to put my ipod into firewire disk mode before it will show up using the Boot with option key setup?

What's going to be the best way to to get this going!!!! help!!!!!

I do not believe that linux can be booted from an external drive on apple hardware currently. OSX I know can be booted from the ipod.

Oh, and I dont think the FAT 32 thing will work out. You'll probably need to make it HFS/HFS+ or whatever.

It may be possible...

Appearantly Yellow Dog can do it, with some work:

what you could do, is make a small root partition, with /boot /bin /sbin /etc...

and then have things like /usr be on the ipod, and be mounted on boot.

that would save a lot of space on the ibook.
however, i have heard of people talking (it was a while ago, so i dont remember the outcome) as if you can boot gentoo from external firewire, because OF supports it. and when you put the ipod in firewire disk mode, thats all it is, a firewire hard disk.

i think you could find the post lying around here, in this forum, but it was a while ago.

Could a more experienced community member explain why it is that booting linux off a firewire drive on Apple hardware is so difficult?? This is a key issue for me (as I"m sure it is with many users). I'd like to know where the onus lies to fix it (on Apple or on the linux community or both)

I'm trying to avoid any linux partitions on my ibook hdd, I'd just like to be able to hook up a gentoois'ed ipod and boot. My ibook hdd is already chocca block with all my Fink X Stuff and loads of other apps and files.

I don't know much about open firmware and booting on Mac's but I thought it might be possible to simply have a complete gentoo install on the ipod just connect via firewire and boot from that drive. Im not sure I understand the problem from booting from firewire, Openfirmware supports it, the kernel has firewire support, why's it not that simple?

This is something I'm remembering from a long time ago, so the facts are probably off a bit, but it might point you in the right direction.

I read somewhere on macosxhints.com that the iBook's openfirmware can only boot off of certain types of formated disks (ie. HFS, HFS+, UFS...). I think what yaboot (Mac linux's boot loader, for new-world Macs) does is, has a tiny partition of a compatible format which loads the linux system off of whatever format you have it in (ReiserFS, ext2/3, whatever...)

If I'm remembering and understanding correctly, then the problem would be that you'd be trying to boot off of a disk that OF (Open Firmware) can see, but can't understand.

Again, (big) if I'm right, then you could try three things.

1) Install only yaboot on the book. Yaboot would normally load OSX locally, but would have an option to load linux from the firewire disk.

2) The linux kernel now has support for HFS+. I haven't seen any threads about installing gentoo on a HFS+ formatted partition, but hey, lots of stuff is possible. If this were to work, you could format your iPod with HFS+, install linux on it, and hold down option (or f?) to boot from it.

3) The install CD has Firewire modules. Try to just install to the iPod, then when you re-boot, hold down option to get a boot menu. If the install was sucessfull, and OF is your friend, you may be able to do it that way.

Good luck,

Michael

Maybe this this could be of use. It shows how to install and boot OS X from an iPod and has some thoughts about the iPod harddisk. Also, they seem to be hinting at a forthcoming guide to do the same thing with Linux...

I'd be careful running a complete OS from the iPod if I were you. I read that with too much activity the thing will overheat terribly...

booting from the ipod would shorten its life and i would expect a hard drive crash, its made for music, not an operating system.


thigni why are you avoiding partitions? how many do you have now? mac disk utitily i think only shows one, but there can be a much as 10 if you installed the os9 drivers. partitioning is easy. i avoided partitions when i first used linux. now i partition for osx and linux (boot strap, swap, root )
