comment How to continue redirecting stdout to a file after logrotate moves it?
This only works if you have explicit output commands like echo. The output of third party tools which are called from the script and also output something cannot be redirected to the logger this way

comment Unprivileged lxc container as root
When trying to do the same, I had the log line: Permission denied - could not access /var/lib/lxc. Please grant it 'x' access, or add an ACL for the container root.. chmod +x /var/lib/lxc/ solved it for me. And instead of lxchostuser:165536:65536 I had root:165536:65536 in /etc/subuid and /etc/subgid

comment How to auto-start unprivileged lxc containers?
Does the crontab approach work? On Ubuntu 14.04, I get the "call to cgmanager_move_pid_sync failed: invalid request" error which occurs because PAM, namely libpam-systemd is not involved in the user changing process. You can see in /proc/self/cgroup that it contains sequences like /user/0.user/1.session instead of /user/1000.user/1.session

comment What is the best practise to autostart unprivileged lxc containers on Ubuntu 14.04 64bit?
I found what's different if you use su/sudo instead of ssh: check the file /proc/self/cgroup. The reason must be somewhere around PAM, namely libpam-systemd. I wrote something about this here: askubuntu.com/questions/623789/…

comment iptables packet forwarding to one of two gateways depending on origin
Final report: At the end, I didn't use this solution because of different off-topic problems like ip blacklists on remote side which made debugging extremely complicated. Finally I was happy for every possible source of problems which I was able to exclude, so I chose a hard switchover with a short downtime.

You could also consider removing these packages completely - this might prevent problems when doing updates
