 .El
+.Sh BUGS
+Unlike the original Linux implementation, the "large_file"
+flag is not set automatically when first file larger than
+2GB is created. Instead,
+.Xr debugfs 8
+utility from the e2fsprogs port must be used to manually
+set the flag with `feature large_file` command. Other than
+this, large files are fully supported.
+
+Support for journaling (ext3) is missing, and filesystems that
+have it enabled are treated as plain ext2 filesystems.
+This means that
+.Xr e2fsck 8
+will have to be used to repair the journal when the filesystem
+is to be used in Linux.
