setting up pvgrub on a xen based vps
Good evening everyone,

I am trying to harden a vps further by setting up PAX grsec and SEL.
Currently the vps is using the hosts kernel. My provider has documentation
on how to do this but not on how to do it on gentoo. I have been told i
need the grub legacy format menu.lst. Is there a way I can just generate
my own grub legacy menu.lst or do I need to install grub legacy in its
entirety and use it instead of grub 2? If anyone has a link to a tutorial
that would be greatly appreciated as documentation seems non existent.

Regards

Writing your own menu.lst is easy; just do it manually. Unliked grub2,
grub1 (for want of a better name) does not "scan" your system and try to
write a menu.lst the way grub2 writes a grub.cfg. So don't install
grub1 (and thus overwrite grub2's boot sector code) in the hopes that
you'll get some magic script to write your menu.lst for you.

I'm not sure why you are finding it hard to find resources. I really
can't help you more because I don't know your setup. Obviously if you
are booting some kernel in your virtual machine using grub1 you already
have a menu.lst. Can you use it as a model?

Good Morning Anthony,

I ended up managing, it had been such a long time since I used grub1 and
forgot what was in it. Not to mention this was the first time that I had
done such a thing as well.

I had a few issues which i managed to iron out and im running the current
hardened kernel successfully.

Apologies for any noise

Regards,
Jonathan
