This is irrelevant. As far as I know, no login program uses getusershell()
or /etc/shells. (Usually this is an issue with setting up ftpd: "The user
must have a standard shell returned by getusershell(3)...".)

I see this was answered in other postings.

It might be interesting to have the sshd choose to use chroot depending on
what the user's pw_shell (default shell) is.

Also, don't waste time copying every tool and library; it should work to
simply hard-link the individual files you want (as long as the real
versions are on the same file system).

Good luck,
