Unionfs has been used by some people in simple configurations
with some success, however sendfile() is apparently incompatible with it.
this wasn't a problem until ftpd in -stable recently got upgraded
to use sendfile(). How nullfs works in the same situation is not
know at this time but may have similar problems.
People have been using union mounts and nullfs mounts to populate parts
of gaols. However the ftpds in these gaols cannot any more read files
but instead send randon junk to the clients..
I know about the "here be dragons, slippery when wet" warnings
but the change to 4.x ftpd has removed functionality that some people were
using to provide service to customers. (let's just say they are worried).
all other operations on the gaol seem to work fine.
Julian
