I'm not sure I would copy an old .config file to a new kernel. For
example, a FC1 kernel will have features in it that a kernel.org release
will not have and you'll be making extra work for yourself trying to
backtrack. FC1 kernel source rpms always give you generic, modular
kernel configs in /usr/src/linux-2.4/configs. Just copy that to your
.config file and then make oldconfig if you like.
On kernel.org releases, I've done it so many times, I usually know what
I need on this system. I just start with make xconfig and go from there.
I've only ever worked with 2.4.x kernels and I've always done
make dep clean bzImage modules modules_install install
As long as you're up and running on a stock kernel, you should find a
new entry after reboot in your grub.conf.
If you're running on a kernel.org release, you may have loopback device
issues that prevent the mkinitrd process as part of install from
happening. I'm sure there's a solution to it, just never persued.
I have 1 kernel.org kernel that's set for scenarios where I need a
specific VPN tool. Otherwise, the generic FC1 kernel has been fine.
I can think of numerous reasons the default kernels may not be
acceptable and think it's great what you're doing.
