[olug] howto boot multiple linux partitions?

[Brian Wiese]

Yeah, I gave up on Lilo - couldn't find anything really online that would
support this, grub looks like it can though.

Lilo has a global definition of what 'boot=' and what 'root=', so having
different kernel images on different partitions (different root /) -- I
don't think would work.  In grub you can specify the root partition and
corresponding image to load for each boot choice, so it looks like that
would work... will play more later.

|image=/dev/hda6 (/boot partition of Linux OS or
