 |
|
hi, i'm doing a remote install on a new amd64 machine. i think i'm using a x86 minimal cd, does this matter?
i'm on the chroot step and am getting this error.
| Code: |
livecd ~ # chroot /mnt/gentoo/ /bin/bash
chroot: failed to run command `/bin/bash': Exec format error |
any ideas?

You need a 64bit kernel to run 64bit code. I suggest you use http://www.sysresccd.org/Main_Page to install Gentoo instead. Besides containing both 32bit and 64bit kernels it has some nice built in tools also.

and don't forget to enter "rescue64" at the boot prompt.

awww, so i guess i have to be there physically to swap out the disk then right?
cause i'm away from it, it's locked away.
is there anyway to do it via ssh without rebooting?
or, if i get back to it, could i just use an amd64 livedvd ?

Yes, you can use an AMD64 live cd. It will also work

Bash Commando,
Welcome to Gentoo.
What is the full name of the stage3 file you used?

The stage3 tarball I downloaded (Via "links") is stage3-amd64-20170907.tar.bz2
And I've solved my part of the problem. While I couldn't "chroot" /bin/bash, I cd'd back to the /root directory and ran the following commands:
source /etc/profile
export PS1="(chroot) $PS1"
And I'm now using the terminal in a chroot environment. |

If the command | Code: | | chroot /mnt/gentoo /bin/bash |
didn't work then the changes you are making will not be in the Linux system you are trying to install, you will be performing changes in the installation medium. This is an important point to understand in the chroot command. | Code: | | export PS1="(chroot) $PS1" |
isn't changing your root directory, only the label of your terminal indicator. Trying | Code: | | export PS1="(not chroot) $PS1" |
will show you what I mean. Please read up on the chroot command and get an understanding of how it affects the root directory as this is probably the most common way to fix borked systems and will make your life much easier in the future if you have an understanding of the concept.

HungGarTiger,
Its a lower case 'g' in | Code: | | chroot /mnt/gentoo /bin/bash |
just in case another reader wants to copy/paste from your post.
Everything else you said is spot on.
