Description

Exasol “As-App” installation would overwrite /etc/sudoers.d/90-cloud-init-users when adding the configured exasol user to sudoers to ensure that Exasol can be updated.

This could overwrite existing configuration if cloud-init was used to configure sudoers.

The “rootless” deployment was not affected.

Workaround

Copy /etc/sudoers.d/90-cloud-init-users to a different file name before starting the installation.

Fix

Exasol now writes to /etc/sudoers.d/99-exasol instead.
