[NO, No, NO....]

I'm not talking about making a kernel that will `work` on your
machine. I'm talking about making __the__ kernel that they supplied
with all its modules, etc.

RedHat 7 is a prime example. I put it on a box in the other room.
/usr/src didn't contain ANYTHING after an installation.
However, /usr/include/asm and /usr/include/linux existed, not
as symlinks, but as files that would-have-existed within a
kernel distribution.

So... I did RPM install for the kernel after I found what was
alleged to have been the kernel. Now I had a /usr/src/linux/..., but
of course not /usr/src/linux-2.2.16-22, the binary kernel supplied.
The stuff in /usr/include was not fixed or changed to sym-links and it was
incompatible with what existed in the kernel. These were 2.2 files
with so much incompatible stuff; a 447,099 byte diff if you are truly

The usr/src/linux/.config was the .config obtained off from Linus`
tree, not something provided by RedHat so `make oldconfig` would have
made a "standard kernel" like you download from

Now, looking in /usr/src/redhat/../.., I find some patches that are
impossible to use to patch the kernel to bring it up (or down) to
the configuration used to build the distribution. The default
configuration, before I "installed" the kernel sources was some
empty directories of /usr/src/redhat/BUILD, /usr/src/redhat/RPMS,
/usr/src/redhat/SOURCES, /usr/src/redhat/SPECS, and /usr/src/redhat/SRPMS.
Now there were some patches and other files with no scripts and no
way to actually use them to modify the kernel. I spent hours, putting
them in order, based upon the time/date stamp within the files, not
the file time which was something more or less random. I made a script
and tried, over a period of weeks, to patch the supplied kernel with
the supplied patches. Forget it. If anything in this universe is truly
impossible, then making a Red Hat distribution kernel from the provided
tools, patches, and sources is a definitive example.

Then, to add insult to injury, the 'C' compiler provided would
not create a bootable kernel. It was egcs-2.91.66. To make
a bootable kernel, I had to install gcc-2.96. The list goes on.

I was going to compile a list of innovations that could be
attributed to Microsoft. Once I realized that Ctrl-Alt-Del
was handled in the BIOS, I found that there aren't any.
