I hadn't heard anything about the kernel being moved and it had been a while. I'm old and I do forget sometimes. Dale, from one old `f..t' to another.. here is a little tip I use dozens of ways to aid my sorry failing memory. In ~/.inputrc Something like (verbatim): \M-f: ls -l `find ./ -iname 'bzimage'` after saving ~/.inputrc, type C-x C-r to make readline re-read it. Then anytime you press Atl-f readline will put that command on the cmdline for you. So inside /usr/src/linux, Alt-f enter will dig up bzimage and show any deceitful symlinks for what they are... hehe. May not be that useful .. at least until someone sneaks in and moves bzimage again, but I guess you can imagine the many ways putting things in .inputrc will free you from remembering stuff. Well, what I did was go into Konqueror and look to see where the link was pointing too. It told me exactly where it was. I could have done the same in console but I was logged into KDE already so I just did it the Nintendo way. LOL Yep, I'm only 41 but I feel like a lot older most days. Dale :-) :-)

I've always wondered how on earth people manage who do a lot of kernel testing without exploding due to frustration. Now I know... :) But out of curiosity, and to recap: I can set the version, either in the kernel config with CONFIG_LOCALVERSION or by using a file localversion containing a version string? I am using the first way, don't know the second. Does this then create a bzImage-versionstring file, and make install copies this to /boot/kernel-versionstring (and system.map and .config respectably)? vmlinuz-versionstring.

You can get the same effect by creating a file called localversion
containing the string to add, which saves altering the kernel config. If
you make this a symlink to .version, you even get it incremented
automatically.
If /boot/vmlinuz exists, then it is moved to /boot/vmlinuz.old, and a
*symlink* from /boot/vmlinuz is created to vmlinuz-${VERSION}. If
/boot/vmlinuz did *not* exist before installation, then no symlink is
created.
Instead, vmlinuz-${VERSION} is copied to vmlinuz.
I'm a little confused here... what exactly is in .version? Say if I
wanted to identify the kernel as belonging to a specific machine.
HOST is vm23. Now if I wanted to have an incrementing version string
that included that host name what would I need in .version and how
does the incrementing work?
Do you mean 1 is added to string each time you call make? Can you
show an example of this?
Does .version need to reside in same level as .config? Will a
`make clean' or `make mrproper'... destroy it?

I hope you won't be offended, but the amount of junk files this added

I've certainly never needed it, in several years since 2.4 kernels.
But IIRC it is/was copied over when using these automated kernel

If I remember correctly, it is only used by depmod, and only if you pass
the file name on the command line. update-modules, which calls depmod,
and tends to be the main way that depmod is called (besides in the
kernel Makefile), searches the following directories for the System.map
file:
/lib/modules/${KV}/build
/usr/src/linux-${KV}
/lib/modules/${KV}
/boot
/usr/src/linux
In each directory, it looks for the file in this order:
System.map-genkernel-${arch}-${KV}
System.map-genkernel-*-${KV}
System.map-${KV}
System.map
What this effectively means is that the copy in /boot is a backup copy,
just in case you clean the current build of your kernel
(/lib/modules/${KV}/build is a symlink to the build directory of your
kernel build, which can differ from the source directory)
tl;dr version: It won't blow up immediately, but you might run into
problems later if you `make clean` or `make mrproper` in the build tree
- - or build a different kernel in the same tree.

I also have a unique way of naming my kernels so I can keep up with

well, you can always put the name in the config - and let make install do
the copy. That way you get a nice vmlinuz symlink to the latest kernel
and vmlinuz.old to the older one - and you never have to touch grub.conf
again.
But that would only allow you to have two kernels laying around. Right
now I have these:
no, you can have as many kernels as you want. But there is a vmlinuz symlink
to the latest and vmlinuz.old symlink to the previous installed one.
To be precise, the config option CONFIG_LOCALVERSION appends a string to
the end of the kernel version, which installkernel uses to place the
kernel image.
If /boot/vmlinuz exists, then it is moved to /boot/vmlinuz.old, and a
*symlink* from /boot/vmlinuz is created to vmlinuz-${VERSION}. If
/boot/vmlinuz did *not* exist before installation, then no symlink is
created. installkernel also copies your .config to
/boot/config-${VERSION}, performing the same move and symlink operation.
In addition, if you *do* install the same kernel version twice, it will
move your old version out of the way (to vmlinuz-${VERSION}.old) first,
so even if you do forget to update your .config, you will still have
both kernels.
To see exactly what make install does, read /sbin/installkernel (a
/bin/sh script), as that's all `make install` calls (well, it first
checks for ~/bin/${CROSS_COMPILE}installkernel, and calls it, if it
exists, which allows you to customize the installation process).
Personally, I will set CONFIG_LOCALVERSION to .# or -r0.# on a
second+ compilation of the same kernel version. (My current kernel is
2.6.28-gentoo-r1.2).
