Following the improvement of exFAT, Microsoft CBL-Mariner 2.0.20230426 adds support for XFS root file system.

CTOnews.com, May 10 (Xinhua)-- Microsoft made some very big improvements in Linux exFAT performance in December last year, thanks to Sony, with internal tests showing a gain of nearly 60 percent in some cases. Speaking of file systems, Microsoft has now added support for XFS as the root file system type for CBL-Mariner. CTOnews.com Note: CBL-Mariner is Microsoft's Linux operating system for Azure 1P services and edge devices.

This change was introduced in the latest version of CBL-Mariner, 2.0.20230426, where the update log states "add XFS as the root file system type", "add XFS support to the installer, and allow Mariner to start the XFS file system".

Here are some of the update log contents:

Add a XFS option for Mariner Installer

Add fsck.xfs to initrd

Add XFS module to grub

This change affects the toolchain, and the test method builds a new VHD and starts it, confirming that the root file system is running XFS. In addition, other Linux file systems have been improved and optimized, including F2FS, Btrfs, and EXT4. In addition, the Linux implementation of Microsoft NTFS File system (NTFS3) will also be optimized.

CBL-Mariner version 2.0.20230426 more updates can be found in the GitHub repository.
