I agree, great work by the LFS team.

I never located such an option in loadprocess().
You can always use
su user -c /path/to/daemon
which has been the tried and true way in unix for as long as I can remember.
I suppose one reason why a "-u login" option hasn't been added to loadprocess()
is because mapping the login id to a user id can get tricky in networked
PAM environments. But I conjecture. I haven't studied the rc functiions
to carefully.
Nowadays it's not uncommon for the daemon itself to setuid from the
root user to another user. For example, apache/httpd changes the user id.
You might check to see if Deluge has such a capability.
That being said, even a server as well known as postgresql doesn't change uid.
Hope this helps-j
