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?

dmesg

DMESG(8)						    BSD System Manager's Manual 						  DMESG(8)

NAME

     dmesg -- display the system message buffer

SYNOPSIS

     dmesg [-ac] [-M core [-N system]]

DESCRIPTION

     The dmesg utility displays the contents of the system message buffer.  If the -M option is not specified, the buffer is read from the cur-
     rently running kernel via the sysctl(3) interface.  Otherwise, the buffer is read from the specified core file, using the name list from the
     specified kernel image (or from the default image).

     The options are as follows:

     -a      Show all data in the message buffer.  This includes any syslog records and /dev/console output.

     -c      Clear the kernel buffer after printing.

     -M      Extract values associated with the name list from the specified core.

     -N      If -M is also specified, extract the name list from the specified system instead of the default, which is the kernel image the system
	     has booted from.

FILES

     /var/run/dmesg.boot  usually a snapshot of the buffer contents taken soon after file systems are mounted at startup time

SEE ALSO

     sysctl(3), syslogd(8)

HISTORY

     The dmesg utility appeared in 4.0BSD.
