I am using CentOS 6 and grub 0.97
1. Launched a Virtual Machine (VM) with CentOS 6. (This step is done.)
2. After the VM comes up, copy latest kernel and initrd from remote
server to /boot
through a script present at /etc/init.d/ (This step is done)
3. How to edit grub config file either by command or by script (but
not manually), to update
the new kernel and initrd so that next time it boots up with the
new kernel ?
Put the kernel and kernel-modules rpms in a directory, cd to that
directory, then
# yum install *rpm
The post-install scripts will call grubby which will insert the proper
GRUB menu entry.
FWIW, there is no GRUB legacy equivalent for GRUB2's grub-mkconfig
command so there isn't a way to generate a new one from scratch.
Recently, someone sent me a script, and it contained
/usr/bin/dracut /boot/initramfs-$version.img $version && \
/usr/sbin/grub2-mkconfig -o /boot/grub2/grub.cfg
Where version is set to the value of the kernel version numbers,
like 3.17.3-200
