[gentoo-user] Several arches installed, flag kernel automatically

[Matthias Fechner]

Hi,

I have here two gentoo systems one 32-bit and one 64-bit.

To save space on my harddisk the mounts /home and /boot are used from
both systems.

Now I have the problem with the kernel version.
Both systems running kernel 2.6.18-gentoo-r6.

If I install now the kernel from the 64-bit system it overwrites the
kernel from the 32-bit system.
In the kernel config is a variable available LOCALVERSION to append
some text to the kernel to prevent the overwrite.

Is it possible to global define this variable e.g. in /etc/make.conf?

Thx a lot,
Matthias

I assume you're using "make install" after building your kernel?  I
usually do a "cp arch/[insert your arch here]/boot/bzImage
/boot/kernel-[version string]" (and then one for the System.map)
Would that do what you want?

No :)

I want to use make install and the Makefile should not generate a
vmlinuz it should generate a vmlinuz-$LOCALVERSION.

You know if that is possible?

Thx a lot

At the risk of maybe coming off as slightly rude (not my intention!) -
why not? It is the simplest solution to make sure the kernels don't
interfere with each other.

You could try playing with the makefile I guess - there should be some
sort of instruction in there to tell it where to put the kernel. I would
have a look myself if I had a copy of the kernel stuff to hand.

thx for your answer.
I do it now in the following way:
Set LOCALVERSION in the .config file from the kernel (if you find the
right menu point you can also do it with make menuconfig, but vim is
faster *g*).
Compile the kernel and easily install it with make install.

Then I have the files:
System.map-2.6.18-gentoo-r6-32bit
config...
vmlinuz...

In grub I always have the link to the full name and not to the symlink.

That works fine but if I upgrade to a new kernel I must always update my
grub config file.
Ok that is not so bad but if there would be a solution to solve it with
a symlink I would prefer it :)

Best regards,
Matthias
