I installed GRUB2 and it seams to work fine. However I would like to get the Ext4 filesystem on my computer. I just can't find out how? Can anyone give me an easy tutorial please?
EXT4 with Arch Linux...how?

So GRUB 2 is stable, then? I thought it was in an indefinite holding pattern for the time being. How do you install it from an existing Arch install?

mips said: http://wiki.archlinux.org/index.php/GRUB2> The next generation of the GRand Unified Bootloader (GRUB2) is still under development and therefore all usual points apply. GRUB2 may fry you computer, burn your house, or eat your cat. You've been warned! For most people, except those with more exotic configurations, GRUB2 should just work.Huh. When is the final release supposed to be? And what is everybody's experience with GRUB 2?

No idea, all I know is there are a good few people using it already.
Thanks...And how fast that is done when you dualboot! Used under 10 min! Things are getting noticeable faster!

The procedure I just used to switch my desktop's rootfs to ext4:
- Get a live CD with ext4 support (like systemrescue cd 1.1.4 or more recent)
- [might be necessary with default kernel, I'm not sure] Make sure that you have the latest kernel26 package installed; edit mkinitcpio.conf and add ext4 to MODULES array; regenerate kernel images with mkinitcpio
- Boot using the live CD
- Backup root filesystem to a tar file on a different partition
- Delete the old root fs and create a new ext4 fs in its place (Arch wiki has a section on how to do it)
- Untar the previously backed up fs onto the newly created ext4 fs
- Edit fstab file on the newly extracted fs, change the root partition type to ext4
- I also needed to add rootfstype=ext4 to kernel command line in grub's menu.lst to avoid a non-fatal warning on boot.
That's pretty much it. The whole tar/untar method for cloning filesystems is explained in this guide -- the guide was written for Red Hat, I think, but it's easy to adapt it to Arch's conventions.
It's a bit of an ordeal, and if something goes wrong you're likely to end up with a kernel panic on the first boot. Still, I've done this many times and it should be completely safe when done properly.
By the way, I am now on EXT4! Runs great! Thanks, SysRescueCD and the Arch Linux Wiki. ;)
