Howto Mount gentoo's "/" under FC2 for Normal User access?

Post #1 of 8 (589 views)

Hi,

I know this is a newbie question and most likely can be found in the
archives/googling but I've spent >30 min looking for it to no avail.

I'm still trying to get gentoo up and running and in the meantime, I'm
doing it chroot'ed style in FC2.

chroot /mnt/gentoo /bin/bash

The problem here is that I can't do it as a normal user.

I do

$ sudo mount /dev/hda9 /mnt/gentoo
and then
su -
(root password)
# chroot /mnt/gentoo /bin/bash

I know I can mount it in such a way that normal users can access it. But
the way I'm doing it, I need to have root access. If I type

$ chroot /dev/hda9 /mnt/gentoo

as normal user, I get a permission denied.

I've tried

sudo mount -o users,uid=500 /dev/hda9 /mnt/gentoo

But that doesn't work either.

What about the --bind option? Not sure if that will work or how to use
it.

Thanks.

Why exactly do you need to do it as a normal user? Most of the stuff you do
during a Gentoo install requires root access.

Well.. What I want to do is say.. I have root access to the gentoo box
being set-up, but I don't have root access to the FC2 box.

Say I want to export via NFS my soon to be gentoo box to a 16 way
(hypothetically) 5GHz Linux Cluster and use it's processing power to
compile stuffs. I can mount Filesystems but I don't have the box's root
password.

How do I go about it then??

chroot(2) requires root, so.. you'll need root on any box you build a stage
on.

If you can get the sysadmins on the Cluster to install distcc you can
"steal" cycles from the cluster to compile stuff for your gentoo box.
There are a few things that your gentoo box will have to compile for
itself, but everything else should work well.
