|
.SH DESCRIPTION
|
|
The
|
|
.B mkinitramfs
|
|
script generates an initramfs image. The initramfs is an 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 \-d \fI confdir
|
|
Set an alternate configuration directory.
|

.TP
|
|
\fB \-k

Keep the temporary directory used to make the image.
|
|
|
|
.TP
|
|
\fB \-o \fI outfile
|
|
Write the image to
|
|
.IR outfile .
|
|
|
|
.TP
|
|
\fB \-r \fI root
|
|
Override the
|
|
.B ROOT
|
|
setting in
|
|
.IR mkinitramfs.conf .
|
|
|
|
.TP
|
|
\fB\-\-supported-host-version=\fIhversion
|
|
This option queries if mkinitramfs can create ramdisks on a running kernel of version
|
|
.IR hversion .
|
|
|
|
.TP
|
|
\fB\-\-supported-target-version=\fItversion
|
|
This option queries if mkinitramfs can create ramdisks for kernel version
|
|
.IR tversion .
|
|
|
|
.SH FILES
|
|
.TP
|
|
.I /etc/mkinitramfs/initramfs.conf
|
|
The default configuration file for the script. See
|
|
.BR initramfs.conf (5)
|
|
for a description of the available configuration parameter.
|
|
|
|
.TP
|
|
.I /etc/mkinitramfs/modules
|
|
Specified modules will be put in the generated image and loaded when the system boots. The format - one per line - is identical to that of
|
|
.I /etc/modules,
|
|
which is described in
|
|
.BR modules (5).
|
|
|
|
.TP
|
|
.I /etc/mkinitramfs/DSDT.aml
|
|
If this file exists, it will be appended to the initramfs in a way that causes
|
|
it to be loaded by ACPI.
