 Kernel support for ext2 file systems has been available since FreeBSD 2.2.

 ====
 This driver can also be used to access ext3 and ext4 file systems.
-The man:ext2fs[5] filesystem has full read and write support for ext4 as of FreeBSD 12.0-RELEASE.
-Additionally, extended attributes and ACLs are also supported, while journalling and encryption are not.
-Starting with FreeBSD 12.1-RELEASE, a DTrace provider will be available as well.
-Prior versions of FreeBSD can access ext4 in read and write mode using package:sysutils/fusefs-ext2[].
