NAME
rdsetroot
—
insert disk image into RAMDISK
kernel
SYNOPSIS
rdsetroot |
-s kernel |
rdsetroot |
[-dx ] kernel
[disk.fs] |
DESCRIPTION
The rdsetroot
utility inserts the file
disk.fs into the reserved space inside a RAMDISK
kernel. If disk.fs is not specified,
rdsetroot
reads from standard input.
The options are as follows:
-d
- Debug.
-s
- Print the size in bytes of the reserved space in the RAMDISK kernel. No insertion or extraction is attempted.
-x
- Rather than inserting, extract the disk.fs image. If
disk.fs is not specified,
rdsetroot
writes to standard output. The disk can be made accessible using vnconfig(8), filesystems can be manipulated, and finally re-inserted into the RAMDISK kernel.
