Hi! A great article about FileVault!
But I am wondering if the following could be potential problem...
AFAIK, journaled HFS+ is the default filesystem for Panther. FileVault works by creating a loopback block device (the *.sparseimage file) and FileVault / Disk Utility will also format the block device as journaled HFS+.
Now we have a situation of a journalled FS running on top of another journalled FS. I _suspect_ this will lead to:
1. performance penality, and/or, worse,
2. possible deadlock in the kernel.
Is it something to worry about? Should users turn journalling off when mounting the sparseimage?

Thanks for the kind words, I really do appreciate them !
I do not think that there is anything to worry about. Indeed, file system journaling is handled by Mac OS X in a very efficient way and should not have any performance or stability impact on your installation.
