It means the System.map in /boot is the one from your last kernel. Copy the
one created in /usr/src/linux when you compiled your kernel to /boot.

This part of the Makefile is only for
$ make install
Which you are not recommended to do. Make bzImage creates the kernel, but
doesn't move *anything* out of that directory and onto the system.
That would be the territory of make install.
Again, don't use make install.

Cha-ching! This is the correct thing to do!

Don't worry. It is a convention (and a useful one) when compiling a
new kernel to put the new kernel in /boot as vmlinuz_${version}, and
the same System.map, etc, and then link to the one you just made with
ln -s vmlinuz_${version} vmlinuz
This way, if your new kernel is crappy, just change the links to point
back to the previous kernel etc.

Redhat distro comes with a precompiled kernel, *and* another for SMP
machines (multiple processors), these are not needed once you
recompile a kernel for yourself.

Dunno.

Seems ok to me, but then my .procmailrc forces html mail through lynx to
convert it to plain text :-)
