Howto log multiple sftpd instances with their chroot shared via NFS

[Nico Kadel-Garcia]

I'm staring at this thread, and all of this complexity, and trying to
figure out "why are you hurting yourself doing this"? In the amount of
time burned trying to integrate hundreds of NFS mounts and chroot cage
configurations, you could have "vsftpd" to support FTPS rather than
SFTP, gotten clean isolated upload and download cages without having
to embed /dev/log in the chroot cages, enabled much simpler and stable
automounting, and spent the rest of the time on the lobbying effort
necessary to convince your user community to switch to FTPS enabled
clients.

Unless you have some compelling need for SSH key based access, why are
you spending these cycles on this work?
