Package: openssh-server
Version: 1:5.1p1-4
Severity: wishlist
Tags: patch

See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487325
(I guess the resolution of that bug report was for sshd to
treat empty $SSHD_OOM_ADJUST the same as unset
SSHD_OOM_ADJUST)

This patch to /etc/init.d/ssh turns off SSHD_OOM_ADJUST if
attempting to write to oom_adj would just create useless log
noise.

I got the detection method from
http://osdir.com/ml/linux.openvz.user/2008-07/msg00045.html
but there might be something better.  (I don't know why the
openvz guest kernel doesn't just make oom_adj 0444 instead
of 0644.)
