.Sh DESCRIPTION
|
|
This program compresses a kernel using
|
|
.Xr 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.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width flag
|
|
.It Fl v
|
|
Verbose mode, reports how much memory is being used by the kernel
|
|
after compression. Also allows you to check to make sure your kernel
|
|
is not going past the 4MB boundary.
|
|
.It Fl l Ar loadaddr
|
|
Specify the address to load the kernel into memory at.
|
|
.Sh DIAGNOSTICS
|
|
The
|
|
.Nm
|
|
utility returns with exit code 1 if given invalid arguments.
|
|
Exit code two means
|
|
.Nm
|
|
was unable to read or process the kernel file.
