grub backport and ext4 support?

[Nicolas KOWALSKI <niko@petole.demisel.net>]

Hello,

I have installed the linux-image-2.6.30 on my Lenny system to be able
to use the ext4 filesystem. I converted my ext3 /home partition
without problems, and it works perfectly, faster.

Would it be safe to also convert my ext3 root partition (no /boot
here) to ext4 if I upgrade my grub installation to the one provided by
the backports?

Thanks,
