the current status of nullfs, unionfs

[Mikhail Teterin]

Hello!

The respected manual contain dire warnings, but the Google search suggests, 
the situation is not *that* gloomy.

For example, according to http://kerneltrap.org/node/652 , nullfs was used on 
Bento-cluster two years ago in 2003.

Is anybody working on this file-systems? Any plans, rumours?

What about the `union' option to regular mounts? Is that safe to use?

Thanks!
