+.SH DESCRIPTION
+The
+.B update\-initramfs
+script manages your initramfs images on your local box.
+It keeps track of the existing initramfs archives in /boot.
+There are three modes of operation create, update or delete.
+You must at least specify one of those modes.
+
+The initramfs is a gzipped cpio archive.
+At boot time, the kernel unpacks that archive into RAM disk, mounts and
+uses it as initial root file system. All finding of the root device
+happens in this early userspace.
+
+.SH OPTIONS

+
+The use of "all" for the
+.I version
+string specifies

+to execute the chosen action for all kernel versions, that are already known
+to
