mount nullfs

[Claudiu Pruna]

Hi list,

I was wondering, in OpenBSD is there an equivalent to FreeBSD's
mount_nullfs or to Linux's mount -o bind ?

Sure; it's in the attic .. don't wake the spiders!

I use a local NFS mount when I want to accomplish this.  It drags in a lot
of complexity, but it has worked for me for years.

The question is if implementations still sucks as before years

It means mount_nullfs doesn't exist anymore (it's in the attic) and a 
local NFS mount works.  I said nothing about performance.  I haven't 
tested that and don't really care.

Back when nullfs existed, it had serious problems (mtime not updating, 
etc).  I'm sure that's why it went away.

I can't call a local NFS mount a perfect solution (there's a *lot* of 
complexity added there) but it does work at least for my purposes and 
satisfies everything I used to use null mounts for.

[Robert Halberg]

Does this mean that the performance of a local NFS mount is actually better
than that of mount_nullfs?
