> Starting with version `101.2408.0004`, Defender for Endpoint on Linux no longer supports the `Auditd` event provider. We're transitioning completely to the more efficient eBPF technology. This change allows for better performance, reduced resource consumption, and overall improved stability. eBPF support has been available since August 2023, and is fully integrated into all updates of Defender for Endpoint on Linux (version `101.23082.0006` and later). We strongly encourage you to adopt the eBPF build, as it provides significant enhancements over Auditd. If eBPF is not supported on your machines, or if there are specific requirements to remain on Auditd, you have the following options:

-Support added for hardened installations on non-executable `/var` partitions. Beginning with this release, antivirus signatures are installed at `/opt/microsoft/mdatp/definitions.noindex`by default, instead of `/var/opt/microsoft/mdatp/definitions.noindex`. During upgrades, the installer attempts to migrate older definitions to the new path unless it detects that the path is already customized (using `mdatp definitions path set`).

During upgrades, the installer will attempt to migrate older definitions to the new path upon detecting a non-executable `/var`, unless it finds that the path has already been customized (using `mdatp definitions path set`).
