+.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
+.TP
+\fB\-k \fI version
+Set the specific kernel version for whom the initramfs will be generated.
+For example the output of uname \-r for your currently running kernel.
+This argument is optional for update. The default is the latest kernel version.
+
+The use of "all" for the
+.I version
+string specifies that
+.B update\-initramfs
+should operate on all installed kernel versions (with \fB\-c\fR), or
+on all installed kernel versions that already have an initramfs
+(with \fB\-d\fR or \fB\-u\fR).
+
+.TP
+\fB\-c
+This mode creates a new initramfs.
+
+.TP
+\fB\-u
+This mode updates an existing initramfs.
+
+.TP
+\fB\-d
+This mode deletes an existing initramfs.
+
+.TP
+\fB\-v
+This option increases the amount of information you are given during
+the chosen action.
+
+.TP
+\fB\-b \fI directory
+Set an different bootdir for the image creation.
+
+.TP
+\fB\-h\fR, \fB--help\fR

+.B update\-initramfs.
