Legacy GRUB to GRUB2

Legacy GRUB to GRUB2

[Yash Jain]

Hello All,
I am using a legacy grub boot-loader with patches provided by GRUB-IMA
for software integrity and  also i am using trusted GRUB for few
families.
Now i have to upgrade it to the advanced kernel(2.6.37) which will be
loaded on ext4 DOM,
Could you please let me know how can i upgrade to GRUB2(because
trusted GRUB is based on legacy GRUB) or it is still fine if i can use
the legacy GRUB to load kernel 2.6.37.
and also could you let me know that how can i build the legacy GRUB on
a 64bit machine - when ever i try to build it gives me a error "error:
GRUB requires a working absolute objcopy; upgrade your binutils".

Thanks and Regards,
Yeshpal Jain.

Treacherous GRUB isn't our software. Moreover it puts your freedom in
danger. For more info http://www.gnu.org/philosophy/can-you-trust.html.

Grab the tarball, then ./configure && make && sudo make install && sudo
grub-install /dev/sdX, replace X with boot drive. You can either reuse
your GRUB legacy config by putting following in grub.cfg:
legacy_source /boot/grub/menu.lst
Or generate modern grub.cfg with
grub-mkconfig -o /boot/grub/grub.cfg

We don't support GRUB Legacy anymore.

I'm still using GRUB-legacy with "linux-2.6.38-gentoo-r6", and it
works perfectly. I'm not using any patches provided by GRUB-IMA, but I
doubt Linux developers have changed anything that would break those
patches (or any other boot loader that supports Linux), and I doubt
there's any reason for you to switch to GRUB2 in the short term.

In the longer term, eventually you'll need to switch to a boot loader
that supports UEFI (the firmware/BIOS that GRUB-legacy relies on is
slowly being deprecated). For Linux your choices are limited to GRUB2
and ELILO, and neither of these boot loaders have any support for
ensuring boot files haven't been tampered with. If you have a strict
requirement for that (e.g. Dept. of Defence or something), then you
may have no choice but to switch to an OS that cares more about your
security than the freedom of malicious attackers.


Cheers,

Brendan

This message is obviously a trolling one in an attempt to start 2
flamewars. Since both topics have been previously widely discussed on
this ML, consider this thread closed.
