Just to double check that your not making the same error as me...
Are you mounting your boot partition then copying the kernel over your
old kernel then umount the boot partition??

Should I mount my /boot partition before doing what I described?
Without doing any manual mounting after boot up:

bash-2.05b# mount
/dev/hda3 on / type ext3 (rw,noatime)
none on /dev type devfs (rw)
none on /proc type proc (rw)
none on /dev/shm type tmpfs (rw)

Its been a while since I've done this but I remember feeling very
silly after making the same mistake..
From memory normal systems never mount your boot partition as a part
of the system startup, so after you've made the new kernel you need to
mount the boot partition then copy the kernel over the top of the old
one (make a copy of the old one first). There is a way of using
multiple kernels and just choosing the one you want at the grub boot
menu, but I've not done this before so ask around a bit.
If you re-read the last few steps in the gentoo install handbook it
should be a little clearer.

The boot partition will be mounted on boot if it is listed in /etc/fstab.
It is not usual practice to mount the boot partition though, unless
you're actually doing something to it (security reasons), such as putting
another kernel there. What you need to do is mount the boot partition,
compile your kernel, move bzIamge and System.map to /boot.

If you want to have the option of booting to multiple kernels, simply copy
your new bzImage to a file with a different name, such as
kernel-new-version, same with System.map, and then add another entry in
grub.conf, similar to the one that is already there, but with the kernel
parameter referring to your new kernel file.

I'm sorry, it will not be mounted at boot if it has the noauto option in
/etc/fstab. My mistake.

Are you absolutely sure?

Was agpgart originally as a module? make modules_install doesn't remove
entries from your /lib/modules directory. It will only add them.

No. I was told that and it's wrong:( Sorry.

I looked at the Makefile and it removes the /lib/modules/version/kernel
directory and then it recreates it. Sorry about that.

Thank you! I am able to install a new kernel now that I mount the
/boot partition before installing. A couple questions though:

Manually copying the bzImage works great after mounting /boot, but
make install never works for me. What could be the problem there?

Can I delete everything in /boot when /dev/hda1 is NOT mounted?

You have to write a kernel installer script yourself. Read the Makefile.

Don't worry. I knew modules_install removed everything, but I also thought
something could had change since 2.4.x; then I looked into the Makefile :-)

Best regards,

If you have a /boot partition, there should be nothing in /boot if the
/boot partition is not mounted. Yes, if the boot partition is not
mounted, you can delete anything in the /boot (the mountpoint) in the
/ partition. Just be damn sure that /boot is not mounted (use 'df')
before you try this.

HTH,
