Chapter 350
Modifications to /stand/system
Beginning in HP-UX 11.0, direct editing of the/stand/system files for
kernel configuration purposes (for example, to add or remove drivers, or
modify kernel tunables) has been deprecated. In HP-UX 11i Version 1.5
(B.11.20), the kmsystem and kmtune commands are required in order to
make changes to the /stand/system file. See the kmsystem (1M) and
kmtune (1M) manual pages for more information.
CAUTION Editing the /stand/system file directly may result in the inability to
generate a new kernel via the mk_kernel or config commands (see
mk_kernel (1M) and config (1M)). Use the kmsystem and kmtune
commands to edit the /stand/system file.
