Re: Re: Re: install 2nd HD G5
You're right that I don't need to do the source thing. I do have a
question about "chroot /mnt/ur.sdb3.mnt.pt /usr/sbin/ybin" however.
By doing this command, will ybin now access the modified yaboot.conf
in sdb3? What is it that chroot is doing in this command? I realize
this is a basic question, but I'm kind of fuzzy on what the function
of chroot is.
Things get complicated, and "chroot" is a way of simplifying the
situation. Most commands do not run in isolation, i.e. they're not
statically compiled nor run independent of support files. As a
consequence "chroot" allows you to run "that" command in the environment
that it was intended to run. So by doing a chroot on the ybin, you not
only selected the proper yaboot.conf, but also you used a different
ybin, i.e. the one on your installed system and not the one on the
ubuntu livecd. It then used the OF support files on *your* installed
system and everything else that your yaboot.conf is implicitly relying
upon. It's really pretty nifty.
