Hi,
this makes dirmngr fail to start when:
root@ara2:~ # fgrep logo /etc/profile
linux_logo -uy
Excerpt from running sh -x /etc/init.d/dirmngr start:

Using “su -” m̲a̲k̲e̲s̲ the shell interactive!
Actually, it makes it a login shell, which i̲s̲ interactive…
The “obvious” solution is to remove the -l option (dash):

Less obvious, start-stop-daemon has a “-c” option to switch the
user before running the dæmon; if you use it directly instead of
LSB’s start_daemon wrapper, you can use that. It’s got quite some
functions that are here possibly useful.
The current code is broken, period. It may not occur during system
startup, but when installing or upgrading the package, the shell
will recognise that its stdin and stderr are a terminal, and it’ll
have a controlling tty and thus be interaceive.
