ISPConfig 3 questions

[till]

Hi,

I'am just searching for the best folder layout for ISPConfig for the websites. My Idea is to implementing it like this:

/var/clients/client[client_id]/web[website_id]/

And then have 2 symlinks for easier shell navigation:

/var/www/[website_domain]/ => /var/clients/client[client_id]/web[website_id]/
/var/clients/client[client_id]/[website_domain]/ => /var/clients/client[client_id]/web[website_id]/

Example:

A website "www.mydomain.com" which has the internal ID 22 and belongs to the customer with the ID 5.

Directory:

/var/clients/client5/web22/

Symlinks:

/var/www/www.mydomain.com/ => /var/clients/client5/web22/
/var/clients/client5/www.mydomain.com/ => /var/clients/client5/web22/

Please post your Ideas and comments on this.

A second question:

a) Shall we create a sytem user for every client, so all websites of a client belong to the same linux user.
b) Shall there be a system user for every website and a linux group for the client. All website users of this client belong to the group of the client.

My preference is b)
