Mount point already in use - when adding subdomains

[kilburn]

The problem is that subdomains create their own directory structure and set up services to do so. Therefore, if two subdomains are pointed to the same mount point, strange things will happen (at least in proftpd, but there may be others, like the backup script, statistics, etc.).

What I did once to solve this problem was to mount them on different mount points (/sub1 and /sub2). After that, login through ssh, remove the /sub2/htdocs folder and create a symlink /sub2/htdocs -> /sub1/htdocs. Done
