+=item --files=filelist
+
+C<filelist> should be a file containing a list of the files to be
+added to the initramfs (one per line). Only those files are added and
+any others are ignored.
+
+When the C<--files> option is not given, all files in C<DIR> are added
+to the initramfs image.
+
+=item --nocompress
+
+This prevents the initramfs image from being compressed.
+
+Linux can boot from uncompressed initramfs images (in fact, faster),
+but they take up a lot more space on disk.
