Bug#473573: openssh-server: oom_adj tweak in init.d prevents upgrade inside vserver

[Olivier Berger <olivier.berger@it-sudparis.eu>]

Package: openssh-server
Version: 1:4.7p1-6
Severity: normal

Hi.

The recently introduced OOM tweak with /proc/processnumber/oom_adj does not seem to be valid for SSH servers running inside a vserver if I get it right.

This results in upgrade being impossible :

Setting up openssh-server (1:4.7p1-6) ...
Restarting OpenBSD Secure Shell server: sshd.
/etc/init.d/ssh: line 78: /proc/22772/oom_adj: Operation not permitted
invoke-rc.d: initscript ssh, action "restart" failed.
dpkg: error processing openssh-server (--configure):
 subprocess post-installation script returned error exit status 1

Maybe this code should execute without any failure to block the whole init.d script to fail, thus allowing to still upgrade (and run) sshd in vservers ?

Hope this helps,

Best regards,

PS.: reporting from a testing host, but found the problem on a unstable vserver guest
