Well, in this case I am running FreeBSD. Does anyone have 1GB RVM mmaped under

coda1# cat vicetab
coda1   /vicepa   ftree   width=256,depth=3

that was set by the vice-setup script (towards the end of it). It asked me for 
the max num of files to store or something like that, and the highest option 
available was 16M files (256^3 ~= 16M)

Ok, so if I really wanted to store 16 million files, that would be 16,000,000 
* 500 = 7.5GB (plus 3000b * num.of.dirs)

Is that even possible? I understand I cannot make a RVM partition larger than 
~ 1.7GB, so what if I made a RVM file 10GB large. Would that be pushing it 
beyond the point of failure?

Thanks for your help,
