make install bug?

make install bug?

[Dale Amon]

When building kernels for my servers I have always done this:

	make INSTALL_MOD_PATH=/usr/src/<target-hostname> modules_install

to dump all the modules into an easily tarballable directory 
to be scp'd to the target host.

However for some reason today it's tried to do a depmod on the 
kernel building machine:

make -C  arch/i386/lib modules_install
make[1]: Entering directory `/VNetLinux/linux-2.4.18/arch/i386/lib'
make[1]: Nothing to be done for `modules_install'.
make[1]: Leaving directory `/VNetLinux/linux-2.4.18/arch/i386/lib'
cd /VNetLinux/scout/lib/modules/2.4.18; \
mkdir -p pcmcia; \
find kernel -path '*/pcmcia/*' -name '*.o' | xargs -i -r ln -sf ../{} pcmcia
if [ -r System.map ]; then /sbin/depmod -ae -F System.map -b /VNetLinux/scout -r 2.4.18; fi
depmod: *** Unresolved symbols in /VNetLinux/scout/lib/modules/2.4.18/pcmcia/3c575_cb.o

depmod:         scsi_unregister_module

	And so forth....


I'm not sure why this started happening, but it isn't nice
behavior at all. I'd call it a bug as I can't imagine why
I'd want a depmod to occur on the build machine.

Have I managed to tickle something that should not be 
happening?

Hmmm, I think I failed to engage brain before fingers. Sent
the files to a non-existant directory... which might be
the thing that tickled it to do the depmod?

depmod runs at build time as a courtesy, to build the modules.dep for
the initial boot, otherwise you get warning messages on the first boot
of a new kernel.  For cross compiling or building for a different
machine, you can turn depmod into a no-op with make DEPMOD=/bin/true.
