How can I do Kernel updates but keep the old kernel as an option in
the GRUB menu? I just looked at systems recently updated and in /boot
all the files for the previous kernel are no longer there.
For now download kernel and run 'rpm -i <kernel>' , this will not delete older
kernel. Though, I would check is old kernel still listed in grub boot menu.
Yep, it still works like a charm. I downloaded and reinstalled 2.6.25.16 after
update to 2.6.25.18 to test a graphics issue and I just collected the rpms into
a single directory like:
02:08 nirvana/srv/www/download/openSUSE_11.0/x86_64/kernel> ls -1 | grep 16
kernel-default-2.6.25.16-0.1.x86_64.rpm
kernel-source-2.6.25.16-0.1.x86_64.rpm
kernel-syms-2.6.25.16-0.1.x86_64.rpm
Then installed them with:
rpm -ivh --force kernel*.rpm
The installed worked just as it should and properly updated
/boot/grub/menu.lst preserving the 2.6.25.18 kernel entries.
NOTE: Above, the --force option was required due to installing an older kernel.
As a general rule _never_ _ever_ use the --force option unless you know exactly
what your are doing. It is the quickest way to thrash your entire rpm database.
