Topic: Change boot kernel remotely

[btech]

Hi All -

I would like to change the kernel that a client SME server is booting into without having to go there (in other words, a remote shell modification to the necessary files followed bty a reboot), and also make certain that the chosen kernel is booted into on every subsequent reboot.

Where are the configuration files for this?  I assume this is handled by the boot manager...?

Thanks,
Jeff

I found /etc/e-smith/templates/boot/grub - does anyone know if I can I modify grub.conf in order to change the boot kernel somwehow?

Thanks,
Jeff

i would like to know to too.
i swap the boot options around in the grub.conf
but i need to change
 /etc/e-smith/templates/boot/grub/grub.conf/UpdateDefault

i dont want the smp version to run

It appears you can simply modify the "default=" setting in /boot/grub/grub.conf.  I don't think it's necessary to modify the template file for this.  I haven't tried it yet (the client is still actively using the server right now) but this appears to be the solution.

I did try that but on reboot the default changes back to 0
the only way i got it to work is to swap the menu options around

Try reconfigure ... I didn't have any problems getting it to work (only edited grub.conf).

Correct.
