It's quite simple: because people that are not 100% comfortable with what they're doing, tend to go for the safest route. And since Workbench shipped with FFS, that's for many people an indication.
For the machines I'm working on now, I dont care much about fast booting, since they are being build as whdload machines. My main machine has indeed a 3.1 FFS boot partition, but that is really only asking me whether to boot 3.9 or 4.1. After that it is SFS all the way. I've had some bad experiences with PFS3 in the past, so I tend not to go that route.
Anyway, despite your disapproval of FFS, I'm glad I can get started
Thanks.
If anything FFS is not safe. It suffers from auto validation and is horribly slow.FFS is easier to corrupt in my experience than sfs.
keep the boot partition under 2Gb and make it SFS, its completely reliable and compatible. Also, sfs2.79 is the latest,and sfs2.77 archive has a bunch of useful tools. not sure why you are using 1.84, although it will work ok.
