Just installed Apollo, and decided to upgrade with the errata packages.
Since there are new versions of the kernel (2.0.36-1 upgrade from
2.0.36-0.7), I decided to do that one as well. I unearthed an ancient
document on redhat's web site on how to upgrade kernels with rpm, and tried
to follow the recipe. No joy.
Here's what happened:
# rpm -ivh kernel-2.0.36-1.i386.rpm kernel-headers-2.0.36-1.i386.rpm
kernel ######################
kernel-headers cannot be installed
/usr/src/linux-2.0.36/include/asm-i386/bugs.h
conflicts with files from kernel-headers-2.0.36-0.7
<snip: multiple messages of the same sort>
OK, in /usr/src we have directory linux-2.0.36 and link 'linux' pointing to
that directory. I tried to rename the linux-2.0.36 directory to something
else, but I still got the same error messages. Q: is there some hidden link
to that directory sitting somewhere else?
Being paranoid, I did
# cp -a linux-2.0.36 linux-2.0.36-0.7
# rm linux
Then
# rpm -ivh --force kernel-headers-2.0.36-1.i386.rpm
which went fine. Result: the directory /usr/src/linux-2.0.36 had been
updated with new files.
Now, the question: IF the include files for 2.0.36-1 are different from
those for 2.0.36-0.7, will the old 2.0.36-0.7 kernel now boot ??? (I don't
want to risk finding out the hard way ...) If so, doesn't Redhat have some
more work to do re: making rpm based kernel upgrades painless?
[If the upgrade had been to 2.0.37, of course, a new directory of that name
would have been created under /usr/src and the question does not come up.]
ANYHOW, here's my take on upgrading from 2.0.36-0.7 to 2.0.36-1. Those who
see errors, please point them out. This procedure worked for me -- both old
and new kernels boot.
// ----------------------------------------------------
# cd /usr/src
# rm linux
# cp -a linux-2.0.36 linux-2.0.36-0.7
# cd /updates/kernels
# rpm -e kernel-iBCS [don't need that one]
# rpm -e kernel-pcmcia-cs [nor that one]
# rpm -ivh kernel-2.0.36-1.i386.rpm
# rpm -ivh --force kernel-headers-2.0.36-1.i386.rpm
# cd /usr/src
# rm linux
# mv linux-2.0.36 linux-2.0.36-1
# ln -s linux-2.0.36-1 linux
# cd /etc
# vi lilo.conf [add a stanza for the new kernel vmlinuz-2.0.36-1]
# /sbin/lilo
# shutdown -r now
