[gentoo-user] grub and what happens exactly when booting.

[Dale]

OK.  The Chief Idiot is going to experiment some.  You ALL know what 
this means right?  Yep, I'm about to really make a mess of things so 
here comes some questions.  This is a result of the /usr and udev crap.  
So, go to -dev and blame them, not me.  ;-)

OK.  I have three drives in my rig.  One is for data files, mounted on 
/data ironically, and has nothing to do with the OS.  So, for that 
reason I'm going to leave it out of this.  So, I now have two drives in 
my rig that are about to be OS related.  sda is a 160Gb and sdb is a 
250Gb.  I'm going to leave the first one, sda, as is and will use sdb 
for testing.  Before I start, I want to sort of get my brain wrapped 
back around this.  It has been a LONG time since I dual booted Linux and 
that was only for a month or so.  I have grub installed on the MBR of 
sda.  My boot partition is on sda1 like most likely 99% of the rest of 
you and it will stay there even after all this is done.  I got /boot 
from the old handbook days.  When I put my new install on sdb, with this 
new initramfs thingy and quite possibly LVM, do I leave grub on sda's 
MBR and just point to sdb for the kernel and init thingy and all will be 
well?

If this all works out, I will be moving everything from sdb to sda 
anyway.  My plan is to get them both bootable, then use one to copy to 
another after I have learned a bit about this mess.  I haven't got that 
far yet but wanting to figure this init thingy out before I'm forced to 
which will only make it taste even worse.

What I am reading so far:

I did a google search and found some others boot this is more Gentoo 
oriented.  So, anything wrong with this as a guide?  Pointers to others 
if they are better would be great.

Here starts a learning process.  It could get bumpy.  lol
