uses Debian9 as the default one.

The support for Debian 9 ended 2 years ago, see https://endoflife.date/debian.

Debian 12 has support for another three years:

Further details

There might be some concerns with the support for glibc since it will change from glibc 2.24 to glibc 2.36, see https://packages.debian.org/source/Bookworm/glibc.

As far as I see, elastic/beats#34921 and elastic/beats#34943 explain some changes about using Debian10 and other changes about keeping support for old versions of glibc, glibc 2.7.0.

Looking at https://www.elastic.co/support/matrix I still see Debian listed as supported unconditionally for Auditbeat, Heartbeat, and Packetbeat in 7.17.x.

Metricbeat and Filebeat have an asterisk for 7.17.x that states **** From 7.17.19 onwards, 7.17.x releases do not support MacOS 10.14, 10.15, CentOS 8, Debian 9, Windows 7, Windows 8 and Windows Server 2008 & 2012 which have reached end of life.. I assume this is meant to cover Debian 8 as well since we don't support Debian 9.

CC @andrewkroh since I know Auditbeat and Packetbeat both use CGO, I don't see 7.17 addressed in elastic/beats#34938 (comment) specifically.

The problem here is that we need to keep updating Go in 7.17 to ensure we keep getting security updates for as long as we are maintaining 7.17.

Hi @jamiehynds, for Auditbeat and Packetbeat need to copy the same quadruple asterisk **** caveat for 7.17.x. Can you handle that amendment to matrix, please?
