Symlinks & chroot - Is it Possible?

I have a few users that I wish to allow FTP access on my 4.9-RELEASE-p4 
system.  I've setup their accounts and added them to /etc/ftpchroot to 
lock them into their login directories.  They are in the standard 
/home/user dirs.

However, I want all of them to have access to another directory 
(/ftp/share) that is setup read-only.  I tried adding a symlink to 
/ftp/share but I've found this doesn't work when the user is chrooted.  
I've Googled on this issue.  A FAQ for  PureFTPd confirms this and 
suggests mount_null.  But the man page for mount_null says that the code 
is beta and may wipe out a file system.

What is the best way to achieve my objective?  If mount_null is it, how 
do I use it?  Do I include it in some sort of login script?  I've set 
these users shells to nologin.  How would that work?
