Unsupported FreeBSD features

Certain FreeBSD features are currently unavailable in CheriBSD, including:

• DTrace

Many other kernel features are not yet well validated, including:

• Non-UFS file systems
• Most optional modules, such as various firewall systems

Alpha ZFS support

The 22.12 release includes Alpha support for the ZFS file system. It is lightly tested, but works without known issues with a hybrid kernel. With the pure capability kernel, filesystems can be created and used, but it must not be the root file system as it currently hangs on boot.

Reporting bugs

Bug reports relating to these under-validated subsystems would be appreciated, and may be submitted to the CheriBSD GitHub issue tracker.
