Gentoo LiveCD for PowerPC G5

tantive writes with this announcement from the Gentoo home page. "Gentoo for PowerPC G5 now available. We're proud to announce the availability of the Gentoo for PowerPC G5 32-bit LiveCD. ISOs are now available on our main OSU mirror. The LiveCD has been tested on a dual 2GHz G5 SMP PowerPC machine with 2.5GB RAM, a 1.6GHz machine, as well as others. It includes pre-released yaboot-1.3.11 bootloader and a 2.6.0-test9 benh kernel. It runs at 100% speed, with fans currently also at 100% (kernel developers are working on slowing down the fans when not needed)." Read more below.

The announcement continues "Installation is possible on the SATA drives. We are now hard at work to create optimized stages, and the store will carry G5 LiveCDs when stage building is finished. Right now you can bootstrap your own G5-optimized system, or use a generic ppc stage3 install with GRP to install Gentoo in 20 minutes. We would like to thank benh (PPC kernel developer) for his excellent work in supporting the G5, as well as all users who tested the ISO, and particularly IBM System Software researcher Eric Van Hensbergen, who provided fantastic test/debug help during the LiveCD development process."

Re:Will the G5 livecd work on G4s?

[MBCook]

Nope. G5 CDs won't work on G4s or G3, but G4 CDs will work on G4s and G5 but not G3s and last but not least G3 CDs will work on G3s, G4s and G5s.

OK, if you didn't survive that, let's put it this way. The CDs work "UP" the processor list, but not "DOWN" (unless there is some specific bug that would prevent the G3 CD from working with the G5s, for example).

So will there be specific G5 distros? Not any more than there are specific Pentium IV distros or Athlon distros.

There is more of an impotus to optimise for G5 though, to exploit its 64-bit-ness. People quite happily run Pentium-optimised Linuxes and indeed Windows programs on their Pentium 4 systems, never exploiting the extra instructions available on these platforms.
If the G5 were just a faster version of the G4 with one or two extra instructions, I expect the same would be true. But since it isn't, people will be much more interested in distributions that are (a) compiled from scratch or (b) available in binary G5-optimised form.

Re:Will the G5 livecd work on G4s?

[MBCook]

That's true, but with Gentoo it doesn't matter that much if you install with a G3 CD. Since everything get rebuilt for your computer from the ground up (or downloaded that's prebuilt for your PC) you'll get those optimisations.

But if you're using the LiveCD as a DEMO CD for Linux, then you're right. But for installing, it's not too big a deal.

PS: Go Gentoo!

Re:Gentoo vs Yellow Dog?

[Otter]

Which is most likely to work? what's the deal with Gentoo (YD is RedHat based... is Gentoo as well?)... I feel like such a newb when it comes to PPC linux.

Basically:

• Yellow Dog is Red Hat based while Debian and Gentoo (and Mandrake and SuSE, if they still exist for PPC) are what they are on x86. Going with what you're familiar with is probably a good idea.
• Yellow Dog, Gentoo and Debian have large PPC communities to provide support. The others don't.
• Personally, I prefer Yellow Dog because its PPC-only focus means it's better about putting in the little bells and whistles for Apple hardware support. YMMV.

Re:Gentoo vs Yellow Dog?

[puregen1us]

Gentoo is source based. Ie. you compile everything from source. That isn't strickly true for the install, a lot of larger packages can be got pre-compiled for specific chips, but generally everything is installed with *your* settings for *your* computer.

It takes a while, but you have nothing installed that you don't want.

I used it on x86 because, In MY opinion, its the best system. SuSE comes close, but gets into too much of a confused mess.

I also found gentoo easier to install than debian. They have a very good docs section, and one of the better forums around. Very helpful and friendly people. They seem to enjoy helping new people to get the best from their computers. Actually makes gentoo a pleasure to use.

YellowDog is a PPC only red hat clone. The only support PPC so are totally dedicated to making everything run well. I think their distro is excellent, and very easy to use. A good newbie install.

SuSE support stopped a while ago.
RedHat never started.
Mandrake might still be around. I'm not a mandrake person.
Debian isn't for me.

Hope thats enough, all thoughts are my own, don't flame me for them. Use whatever you want.

In fact install every distro you can get. You will olny learn more. Choose one you like and stick to it.

Use parted

[justMichael]

You can use parted which is on the Gentoo Live CD and probably others..

From the FAQ: ...Before installing Gentoo, startup with the Mac OS X Install CD. Use the Disk Utility to partition the drive in your machine into two or three partitions. Alternatively use parted from the recent LiveCD, that can handle HFS and HFS+ partitions. Furthermore it is able to shrink a partition so you don't need to delete your whole disk...

The downside to this is that the current Live CD may not work on your box due to a frimware issue, but a fixed iso should be available soon.

Re:Question for Mac Linuxers

[illogic]

I don't think it's a question of users moving away from OS X to Linux, rather it's Linux users deciding to buy Macs rather than Wintel machines. Many Apple Linux users that I know simply wanted good hardware to run Linux on (especially *Books).

Driver support can be easier as Apple computers are much less of a moving target than the myriad x86 laptops, each with their own blend of proprietary hardware. Compare how many models of laptops a company like Sony puts out, and then multiply that by every PC manufacturer... buying an Apple seems like a pretty safe bet.

And after all, they're just plain sexy.
