[tech] Murasoi upgraded to Debian stable "jessie" 8.1

[David Adam]

With the server downtime today, I figured nobody would mind too much if 
routing went away for another few minutes.

I upgraded Murasoi to Debian "jessie" 8.1. Like most of the transitions, 
it was surprisingly smooth.

The only problem I ran into was that our very custom syslog-ng 
configuration needed updating to match the type of syslog messages that 
systemd sends [1][2].

Otherwise, it looks good:

# systemctl status
● murasoi
    State: running
     Jobs: 0 queued
   Failed: 0 units
    Since: Sat 2015-06-13 20:28:39 AWST; 3h 5min ago
