[WHERE PROBLEMS COULD OCCUR]

[OTHER INFORMATION]

Regression could occur at core functionality, which may prevent sos (or its subcommand to work. I consider this regression type as 'low'. That is generally well tested, and we would find a problem at an early stage during the verification phase if it is the case.

On the other end, regression could happen and are some kind of expected at plugins levels. As of today, sos has more than 300 plugins. It is nearly impossible to test them all.

If a regression is found in a plugin, it is rarely affecting sos core functionalities nor other plugins. So mainly the impact would be limited to that plugin. The impact being that the plugin can't or partially can collect the information that it is instructed to gather.

A 3rd party vendor would then ask user/customer to collect the information manually for that particular plugins.

Plugins are segmented by services and/or applications (e.g. openstack_keystone, bcache, system, logs, ...) in order to collect things accordingly to the plugin detected or intentionally requested for.

Sosreport plugins philosophy is to (as much as possible) maintain backward compatibility when updating a plugin. The risk that an ancient version of a software has been dropped, is unlikely, unless it was intended to be that way for particular reasons. Certain plugin also support the DEB installation way and the snap one (MAAS, LXD, ...) so all Ubuntu standard installation types are covered.
