Update deleting default.conf

[MScharnagl]

Summary

Updating a Mattermost-Omnibus install on a bare-metal server with multiple subdomains deletes the (edited) default.conf in nginx conf.d folder, changing the default forward from www to the mattermost subdomain.

Steps to reproduce

Updating Mattermost using "apt upgrade"

Expected behavior

Other configurations should not be altered, not to mention removed without asking.

Observed behavior (that appears unintentional)

Ansible update script seen using "absent" state after new cert was requested.
Relevant syslog:

Possible fixes

Remove/change "absent" keyword for default.conf or alternatively give option to select.
