There are more of them. I'm aware of portmap and some NFS related
daemons. I believe most of of them should be moved from rcS.d/ to
rc[2-5].d/, along with networking and several others.

I do not believe it is needed to add start symlinks in rc1.d/ for udev
as long as it isn't killed by killprocs. Not sure what the current
status is there. Both runlevel 1 and single user mode in Debian is so
broken it is hard to know where to start to make them work properly.
At the moment the only safe and sane thing to do after working in
single user mode is to reboot to recover.

If killprocs kills it in rc1.d/, udev can not have a start symlink in
rc1.d/, as this will cause init.d/rc to not start udev when switching
from runlevel 1 to runlevel 2.

If you keep udev out of this, I agree.

I tried to explain in my previous email, that there probably is no
such case. Either the daemon need special code to stop, and it need
to have stop symlinks in runlevels 0, 1 and 6, or it do not, and do
not need stop symlinks in any of runlevels 0, 1 and 6.
Now I believe the problem I remembered was with start symlinks in
runlevel 1, which can be problematic as the daemon will be killed by
killprocs and not start again when switching from runlevel 1 to

I suspect you are right, that such setup do not make sense.
