Make sure you are logged in as 'root'. I can't imagine why patch isn't
there. Maybe it is in some system utilities RPM. You might do a
man patch to see if it gives any clues as to what you need to do to
make it available.

Even more serious! Maybe these are installed with a C development
RPM. Anyway, you need to rebuild the kernel AFTER the patches
go in.

Well, to shut Linux down, first do crl-alt-backspace to shut down the
X system, then do shutdown -h now
to bring Linux down gracefully. When it says system halted twice,
you can power off without fear of causing a file system problem.
