Hello, With tmpfs being in the tree for the last 2+ years (since OpenBSD 5.5), I would like to ask, besides the "-P" option in mount_mfs, what is the advantage of using mfs over tmpfs?
It seems tmpfs has the following advantages: - Can grow or shrink; shrinks when files are erased. - Can impose definite limits on number of inodes/files (then again, this happens in mfs too). - Dedicated memory structures used, rather than just plonking an entire disk FS onto it. I have seen discussions here: http://marc.info/?l=openbsd-tech&m=139935771507987&w=2 There is a claim that tmpfs is not as stable on that thread, but that was back in 2014 when this was still new. I am willing to write a patch (or series of patches) to remove mfs support if it is deemed to be unused/unnecessary; unfortunately I only have access to an old amd64 machine for testing. Thoughts?
