transfering kernel image to another system

my server system is low on disk. To install a new kernel I think i shall do the following:

1. compile the kernel on another system.
2. copy bzImage along with config, System.map and of course the laodable module in /lib/modules and transfer them to the server.

3. Now, I can remove the server's old kernel to free up the space and put the the files in /boot as well as copying loadable modules to

no,... this is not the way, this way I need to make the drivers the image as well. There's another way, in ubuntu I can make .deb files of the headers and the linux, if I transfer only those two files to the server, I think i can install the new kernel using dpkg. what do you think?

pmerge(8)						      System Manager's Manual							 pmerge(8)

NAME
pmerge - Builds a network bootable kernel. SYNOPSIS
/usr/sys/bin/pmerge bootfile kernel.name new.kernel DESCRIPTION
The kernel, vmunix, is not bootable over the network. The pmerge utility prepends the bootfile onto the kernel image (kernel.name) to cre- ate a new operating system image (new.kernel) that is bootable over the network. Instead of a booting a network loadable kernel, it is sometimes desired to bootstrap link a kernel over the network. In this case, (ker- nel.name) is the name of the sysconfigtab file on the server containing the list of modules to be loaded to the client. These modules are then linked to create a bootable kernel on the client. The pmerge utility is used by doconfig(8) to create a bootable operating system for dataless management services (DMS) client systems to boot over the network. The pmerge utility is automatically invoked by doconfig(8) during the kernel build process and should not be invoked independently. The pmerge utility is located in /var/adm/dms/dmsn.alpha/root/usr/sys/bin on the DMS server. SEE ALSO
