Missing privilege separation directory: /var/run/sshd

Often, openVZ VPSes that are left behind by their providers are stuck with old kernel versions.

For this occasion, my VPS had 2.6.32-042stab127.2 and after an upgrade, the server’s sshd service wouldn’t start on boot.

Missing privilege separation directory: /var/run/sshd

Digging on the problem, I found out that on 2.6.32-042stab134.7 it was fixed.

To temporarily bypass the problem you can create the directory /var/run/sshd yourself and start the service manually:

# mkdir -p /var/run/sshd
# service sshd start

That will bring the sshd back up.

For a permanent fix, you’ll have to edit /usr/lib/tmpfiles.d/sshd.conf with:

d /run/sshd 0755 root root

Then reboot and you’ll see that the service starts without problems.
