[tech] motsugo upgraded to Debian stable "jessie" 8.0

[Nick Bannon]

That was encouragingly straightforward - motsugo's now running jessie,
including systemd.

We had to remove mongodb-server (it could be put back again now).

The old but stll current version of https://tracker.debian.org/pkg/cpu is
still installed, it's in unstable but not actually in jessie or testing
right now.

We ran into http://forums.debian.net/viewtopic.php?f=5&t=113269 :
/etc/profile.d/pythonbrew.sh was breaking/corrupting root's $PATH -
removed.

These filesystems didn't mount on boot, a "mount -av" did work after boot:
away:/space/away/home /away
services:/space/services /services
services:/space/mp3s /mp3s

This would explain it...
https://bugs.debian.org/739721
https://wiki.ubuntu.com/systemd#Remote_filesystem_mounts

We tried adding system units to do it instead:
root at motsugo:/lib/systemd/system# ls -l away.mount mp3s.mount services.mount 
-rw-r--r-- 1 root wheel 234 May  9 01:41 away.mount
-rw-r--r-- 1 root wheel 233 May  9 01:41 mp3s.mount
-rw------- 1 root wheel 311 May  9 01:41 services.mount

...but it's still not happening.

Finally: IMAP problems from dovecot, which is mostly using the
pre-upgrade config. e.g. webmail won't log in...
