I'm using Linux-2.6.14. My application is having one kernel module of large size(approx 8MB), insmoding of that kernel module is taking pretty much time(approx 8Mins). Is there a way to reduce the insmod time? I tried even by modprobe also. (0 Replies)

NEXTBOOT(8) BSD System Manager's Manual NEXTBOOT(8)
NAME
nextboot -- specify an alternate kernel and boot flags for the next reboot
SYNOPSIS
nextboot [-e variable=value] [-f] [-k kernel] [-o options]
nextboot -D
DESCRIPTION
The nextboot utility allows specifying some combination of an alternate kernel, boot flags and kernel environment for the next time the
machine is booted. Once the loader(8) loads in the new kernel information, it is deleted so in case the new kernel hangs the machine, once
it is rebooted, the machine will automatically revert to its previous configuration.
The options are as follows:
-D Invoking nextboot with this option removes an existing nextboot configuration.
-e variable=value
This option adds the provided variable and value to the kernel environment. The value is quoted when written to the nextboot
configuration.
-f This option disables the sanity checking which checks if the kernel really exists before writing the nextboot configuration.
-k kernel This option specifies a kernel directory relative to /boot to load the kernel and any modules from.
-o options This option allows the passing of kernel flags for the next boot.
FILES
/boot/nextboot.conf The configuration file that the nextboot configuration is written into.
EXAMPLES
To boot the GENERIC kernel with the nextboot command:
nextboot -k GENERIC
To enable into single user mode with the normal kernel:
nextboot -o "-s" -k kernel
To remove an existing nextboot configuration:
nextboot -D
SEE ALSO
boot(8), loader(8)
HISTORY
The original nextboot manual page first appeared in FreeBSD 2.2. It used a very different interface to achieve similar results.
The current incarnation of nextboot appeared in FreeBSD 5.0.
AUTHORS
This manual page was written by Gordon Tetlow <gordon@FreeBSD.org>.
BUGS
The nextboot code is implemented in the loader(8). It is not the most thoroughly tested code. It is also my first attempt to write in
Forth.
Finally, it does some evil things like writing to the file system before it has been checked. If it scrambles your file system, do not blame
me.
