I would like to have the www directory to be located on hdb2. This is how I do, I bet there are better ways, but this works fine for me. In the boot-section of /rc/rc_user I do this:

• Create a directory in /mnt for my 1st partition of hdb and change access rights with

mkdir /mnt/disk2
chmod 755 /mnt/disk2

• I have created a directory on the partition called www. Now I change the necessary symblinks to point to this directory with

ln -nfs /mnt/disk2/www /www
ln -nfs /mnt/disk2/www /mnt/bootdev/router/www

• Finally, I mount the partition to /mnt/disk3

mount -t ext2 /dev/hdb2 /mnt/disk2

Maybe I should have mounted the disk earlier in the process, but this works fine.

Hope this helps
