Hello my friends. Edward, you ARE the man! :D Your patch works wonderfully. Inside my virtual machine, I made a new custom distro (based on debian squeeze, but with 2.6.39 kernel, patched with reiser4 native support), and I was able to install it in another virtual machine (/boot as reiser3, / as reiser4 and /home as reiser4). Everything are working fine now. :D Now, I'll burn this new custom distro in a DVD and I'll install it on my notebook (no more VM) to test it. Please, may you tell me if the reiser4 has some auto-defragmentation feature? The compression feature (gzip1) is amazing. If we have auto-defragmentation feature also.....man!!! No words. :D Thank you and the entire reiser4 team. You all are making the difference.
