**Hardened Linux**
|
||
Linux 5.10 Yocto-based kernel ( https://www.yoctoproject.org/ )
|
||
|
||
The Yocto Project Kernel:
|
||
|
||
* tracks stable kernel updates very closely; staying very current with the
|
||
stable kernel,
|
||
|
||
* provides a reliable implementation of the pre-empt-rt patchset (see:
|
||
https://rt.wiki.kernel.org/index.php/Main_Page), and
|
||
|
||
* provides predictable and searchable |CVE| handling.
|
||
|
||
|org| leverages its existing relationships with the Yocto Project to
|
||
enhance development, bug fixes and other activities in the Yocto Project kernel
|
||
to drive |prod| quality and feature content.
|
||
|
||
* Debian Bullseye (11.3)
|
||
|
||
Debian is a well-established Linux Distribution supported by a large and
|
||
mature open-source community.
|
||
|
||
* OSTree ( https://ostree.readthedocs.io/en/stable/manual/introduction/ )
|
||
|
||
OSTree provides for robust and efficient versioning, packaging and
|
||
upgrading of Linux-based systems.
|
||
|
||
* An updated Installer to seamlessly adapt to Debian and OSTree
|
||
|
||
* Updated software patching and upgrades for Debian and OSTree.
