Problems Building Kernel 2.4.9

Looks OK.

my usual build process, BTW, looks something like this:
make menuconfig
make dep clean bzImage modules
su - root    #  you don't need to be root to make the kernel; I compile in
my home directory
make modules_install
cp arch/i386/boot/bzImage /boot/bzImage249
emacs /etc/lilo.conf
# add the appropriate entry to lilo.conf, either by copying an existing
# one, or more likely updating an old one.

All this playing around with symlinks doesn't really gain you
anything. Adding multiple entries to lilo.conf gives you more flexibility
- so, for example, you can keep an old, working, copy of 2.4.9 around so
next time linus breaks things you can go back.

Are those spaces really there? If so, that could be a problem!

Usually the kernels are thrown in /boot. That wasn't always the case, of
course.

What was the output of lilo? This is what I see when I run lilo here:
----
Added linux2410p4
Added linux247 *
Added linux247-debian
Added linux247pre1
Added linux245
Added linux
Added linux-up
Added dos
----
(Yeah, I know, I'm behind the times again.)
The "*" indicates that's the default boot option.

Here's the top from my lilo.conf:
---
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
# message=/boot/message
linear
default=linux247

image=/boot/bzImage2410p4
        label=linux2410p4
        read-only
        root=/dev/hda3

image=/boot/bzImage247
        label=linux247
        read-only
        root=/dev/hda3
---

"uname -a" will tell you unambiguously. I strongly suggest that you _not
break_ the 2.2.18pre21 boot. Use lilo's features :-)
