This is a list of steps as guidelines for OS upgrades.

* create a temporary _group_vars/<new-suite>/system.yml_ in a git branch:

<pre>
8
---
9
system:
10
  distribution:
11
    debian:
12
      codename: bullseye
13
    dc:
14
      codename: bullseye
15
16
</pre>
17
18
* (I often choose ELwing first) ansible-playbook --diff -l Elwing -t apt playbooks/common.yml | tee /tmp/dc.log
19
* apt upgrade
20
* apt dist-upgrade (check if removed packages are problematic)
21
** accept new version of /etc/services and copy-paste content of _local services_ from _/etc/services.dpkg-old_ to avoid having to redeploy all services
22
** do not accept new versions for:
23
*** /etc/smartd.conf
24
*** /etc/snmp/snmp.conf
25
*** /etc/oidentd.conf
26
*** /etc/sudoers
27
*** /etc/rsyslog.conf
