I’ve been doing so for ages, from a BSD PoV (not su -l though¹).
Sometimes su -c, sometimes chroot, sometimes both, rarely dchroot.
But so are my coworkers who are *not* experienced with BSD.
I’ve barely (not even completely) got our admins and systems
running Debian/LSB init scripts by now. Piling even more change
on top of what is currently needed for administration (ever
since insserv…) will not work; people will end with partially
broken systems and blame Debian and go back to use CentOS 5…

But the start-stop-daemon documentation seems to imply (please
correct me if I’m wrong) that it’s for starting (and stopping)
specific executables, as dæmons, with pidfiles, etc. – not for
just running some shell code (which may or may not start other
processes and/or dæmons) as another user.
Taking dirmngr as example again:
output=$(su -c ". /lib/lsb/init-functions && umask 027 && start_daemon -p $PIDFILE $DAEMON --daemon --sh" dirmngr) || return 1
eval "$output" || return 1
Before preparing the NMU¹, I searched long and wide for something
using start-stop-daemon which could replace this piece of code,
and found it not.
① Note I did NMU dirmngr to remove the -l from the su call,
which was causing problems.
