This is from 2.2.3's make file:
#
# INSTALL_MOD_PATH specifies a prefix to MODLIB for module directory
# relocations required by build roots. This is not defined in the
# makefile but the arguement can be passed to make if needed.
#
I'm assuming that a:
make INSTALL_MOD_PATH=/home/customer/spa/kernel modules_install
will install to /home/customer/spa/kernel/lib/modules
I took the modules_install rule out of the kernel and made a shell script to
read the make file for the version (needs awk) and install the mods into a
specified dir (it makes <dir>/<kernel version> if need be)... See attached
file.
Anyone thing I'm wrong on this? Feed back is welcome... Too negative of
feedback is /dev/null'd
> I'm building kernels on a server right now that are for other machines.
