Enable pure-ftpd's virtualchroot
Enable pure-ftpd's virtualchroot in service configuration on install and update to allow ftp users to view the log symlink.
For Debian it is as simple as setting VIRTUALCHROOT=true in /etc/default/pure-ftpd-common, as the package comes compiled --with-virtualchroot. I am not sure about other OS's.
If anyone is compiling from source, they will need to make sure to compile --with-virtualchroot, this should maybe be placed in documentation.
