DESCRIPTION

refuse is a reimplementation of the file system in user space subsystem. Operations are transported from the kernel virtual file system layer to the concrete implementation behind , where they are processed and results are sent back to the kernel.

It uses the framework provided by the puffs(3) subsystem, and, through that, the kernel interface provided by puffs(4).

SEE ALSO

puffs(3), puffs(4)

HISTORY

An unsupported experimental version of refuse first appeared in NetBSD5.0.
