The answer is: Yes. Even Olaf "Olsen" Barthel suggests NOT to use FFS2 - switch to SFS/00 or SFS/02. Most people use SFS/00 for the boot partition and SFS/02 for everything else - if you feel "experimental" you might use JFXS for non-bootable partitions, I haven't tried this yet. The difference between SFS/00 and SFS/02 is the usual, the last one is newer and is able to handle bigger hard disks and partitions - it should be explained in the the docs located in the documentation drawer.
