5.1 on a production box with some small problems (su, linux emu 7)

i run 5.1 on one of the inhouse production boxes successful. there are 
only 2 small points witch are a pain and i found no solution. box was 
fresh setup with 5.0 then cvsuped to 5.1.

1. when starting some scripts su doesnt return from the shell and hangs 
on boot. when starting manually i get "tty output stopped". with exit 
there is a way out of this shell, but i havnt found a solution. most of 
the scripts runs since 3.x, at least 4.x and was working up to 4.8. one 
of this scripts is the pervasive sql server startup script which is part 
of the pervasive server for linux. using #!/compat/linux/bin/sh doesnt 
help. there are 2 lines in it starting sqlmgr and psql with:
echo "commands...." | /bin/su - psql || exit 1
after the 1st one tty output is stopped. the other script is vmware and 
vncserver related and uses linux emu too.

2. the pervasive sql server (running under linux emu 7) has a daemon 
named mkded witch was running since a long time till 4.8. on 5.1 i have 
the strange problem, that if the daemon is startet with the -start 
option (which should put it in the background) there is no listener 
opened. netstat -an doesnt show a listener on port 3351, but the daemon 
is running without logging any error. when starting mkded with the 
-console flag whitch keeps it in the forground the listener is opened 
and a connection is possible. i meanwhile use screen, starting up with a 
detached session and the -console flag to have it running, but a 
solution would be really great because this slows down the database 
access dramaticly.
