[For anyone tuning in late, I'm having a problem specifying MFS file systems in excess of ~500MB without using -F, and I'm trying to understand why. The one comment I have received so far is that max MFS size is a function of total swap space. I'm now disagreeing...] Actually, it appears swap size is not an apparent function of MFS file systems. Even at a 2GB of swap, MFSs over 507MB (+/-) won't work unless the -F option is also given (although I'm not sure of the impact). Therefore, I don't know if this qualifies as a bug or not...
