I'm stuck trying to get the new initfs flashed onto my N800.

I downloaded initfs_flasher.tgz on my SD card, opened up Osso-Xterm and unpacked the archive (initfs_flasher.tgz), changed to the initfs_flasher directory and tried to run the initfs_flash script but it gives me a Permission Denied error. So I did a "sudo gainroot," verified I was root, and got the same error. After that, I installed Dropbear server, SSHed in as root, ran the script again, and got "Permission Denied" again.

The only time I get a different result is when I just type "sudo ./initfs_flash" and no error message occurs, just a command prompt.

Am I doing something wrong? From what I gather, I've followed all the directions 100%.

It seems as though just typing "./" is causing the problem - I'm using the built in Busybox (v1.1.3) shell, is that correct? I've looked around and haven't found any information that says a different shell is necessary.
