NAME

mk_kernel - load a kernel conﬁguration from a system ﬁle

SYNOPSIS

/usr/sbin/mk_kernel

[-o path_name ][-s

system_ﬁle ][-v]

DESCRIPTION

mk_kernel reads conﬁguration information from the system ﬁle (see system (4)) and applies those

changes to a kernel conﬁguration (see kconﬁg(5)).

mk_kernel performs a function similar to that of

kconfig -i, but has some semantic differences in order to preserve compatibility with previous

releases. mk_kernel will build a new kernel executable only if needed to effect the requested changes.

mk_kernel may reuse existing kernel executables when possible.

Options

mk_kernel recognizes the following options.

-o path_name

Specify the target kernel path.

If the target kernel path speciﬁed is

/stand/vmunix, changes are applied to the currently

running kernel conﬁguration. They will take effect immediately if possible; otherwise, they

will take effect at next boot.

If the target kernel path speciﬁed is of the form

/stand/conﬁg

/vmunix, changes are

applied to the saved kernel conﬁguration named conﬁg. The changes will not take effect at

next boot unless that saved kernel conﬁguration was already marked for use at next boot.

If the target kernel name is a single word containing no slashes, that name is used as the

name of a saved kernel conﬁguration. The changes are applied to that saved kernel

conﬁguration. The changes will not take effect at next boot unless that saved kernel

conﬁguration was already marked for use at next boot.

If the target kernel path is not one of the forms speciﬁed above, then

mk_kernel exits with

an error. Other locations for kernel executable ﬁles are no longer supported.

If the

-o option is not speciﬁed, the changes are applied to the kernel conﬁguration called

hpux_test. The changes will not take effect at next boot unless that kernel conﬁguration

was already marked for use at next boot.

-s system_file

Specify the HP-UX system description ﬁle. If this option is not speciﬁed, the system ﬁle

/stand/system is used. For details see system (4).

-v Verbose mode. (Has no effect; retained for backward compatibility.)

RETURN VALUE

mk_kernel returns 0 upon normal completion; it returns 1 if an error occurred.

DIAGNOSTICS

Messages and warnings are sent to

stderr. Messages from kconfig and other commands are

displayed when invoked from mk_kernel. Errors cause mk_kernel to halt immediately; warnings

allow the program to continue.

EXAMPLES

mk_kernel -o /stand/vmunix

Uses the default HP-UX system description ﬁle /stand/system. The changes are applied to the

currently running kernel conﬁguration, marked to take effect at next boot.

mk_kernel -s /mnt/altsys/stand/system.new

Uses the system description ﬁle /mnt/altsys/stand/system.new.

mk_kernel -s /stand/system -o fred

Uses the system description ﬁle /stand/system The changes are applied to the saved kernel

conﬁguration called fred.
