You'd create a test filesystem with the appropriate feature flag set
(mkfs.ext4 -O richacl2 / mkfs.xfs -m richacl=1), RichACLs are not
enabled by mount options anymore. This will obviously require versions
of e2fsprogs / xfsprogs that understand the feature. If you want
coreutils support which isn't strictly necessary, you'll need the
patched version too. Other than that, it's really simple.
