KZIP(8) BSD System Manager's Manual KZIP(8)NAME
kzip — compresses kernels
SYNOPSIS
kzip [-v] [-l loadaddr] kernel
DESCRIPTION
This program compresses a kernel using gzip(1) to reduce its disk storage
requirements. It does not reduce the memory footprint once loaded into
memory. You lose all the symbols, so usability is limited. Its main
usage is making kernels for install and fixit floppies, etc.
The following options are available:
-v Verbose mode, reports how much memory is being used by the kernel
after compression. Also allows you to check to make sure your ker‐
nel is not going past the 4MB boundary.
-l loadaddr
Specify the address to load the kernel into memory at.
DIAGNOSTICS
The kzip utility returns with exit code 1 if given invalid arguments.
Exit code two means kzip was unable to read or process the kernel file.
SEE ALSOgzip(1)HISTORY
The kzip command appeared in FreeBSD 2.0.5. Obtained from Linux via
386BSD -- based on tools/build.c by Linus Torvalds, and ported to 386BSD
by Serge Vakulenko.
