MFS is simply a UFS which uses (swap-backed) memory instead of a physical disk; it relies on the filesystem to avoid touching blocks that it doesn't need, and on the VM system to avoid wasting memory on allocated-but-untouched address space. Historically, MFS would waste time copying disk blocks twice on their way to the user, but I think this may have been fixed by Matt Dillon. -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
