FTP directory access

[phpguy]

I'm using Debian's proftp and would like to allow a user to access only certain directories:

Namely:

1) /var/www/

and

2) /opt/myapp/

However.... It seems that I can only do one or the other -- not both. /etc/proftpd/proftpd.conf is the the file that I'm supposed to edit... Now, I can do DocumentRoot /var/www or I can do DocumentRoot /opt/myapp/ but I can't do both

What is the general practice for this? Should I create separate users? One for one directory and one for another?

Here is such question greatly described

ProFTPD mini-HOWTO - Symlinks and chroot()

The main idea is that in Unix systems you could 'mount' your directories in any point in filesystem tree. For example, you could easily mount your '/etc' directory to '/mnt/etc_dup':

mkdir /mnt/etc_dup
mount --bind /etc /mnt/etc_dup

and access your '/etc' through '/mnt/etc_dup'. Symlinks are easier to use, but not works after 'chroot' that ProFTPD uses to set DefaultRoot for user. For details see link above or file sharedsubtree.txt from kernel docs.
