ignoring the fact that venti doesn't know for (fossil) users, does no
authentication ....
that's quite a radical shift from unix-like behavior. unix permissions have
always been enforced at the file, not the block level. this could lead to
situations where you can read parts of a directory entry but get Eperm
on other parts. or where you could get Eperm in the middle of a file.
idle questions:
· has anyone considered making venti extent rather than block based?
· does anyone have any performance numbers on resonably fast/modern
hardware for venti?
