A PFS is more like a namespace, I got that.
It's a logical separation within HAMMER's B-Tree. Things
(inode/dirents/data/etc) that belong to PFS#1 are logically clustered
within the tree, and the same for PFS#2,3,4,etc. The only different
one is PFS#0 which is what you have by default after newfs_hammer.
PFS#0 includes all the other PFSes. Having logically clustered
sub-tree and exported to userspace via PFS symlink makes
mirror-copy/etc easier to implement when there are certain target
directories that you want to copy to/from.
Sounds like some sort of namespace to me but I get the point.
But you seems to have great knowledge about this so feel free to write
the missing doc to enlighten the rest uf us.
