I currently have two Gentoo installations. #1 install is as follows:

sda1 /boot
sda2 swap
sda3 / (root)


The #2 Gentoo install is just awaiting the kernel to be compiled and I need to make the /etc/fstab file.

So far I have this:
sda2 swap
sda4 / (root)

My 'guess' is that I would edit the /etc/fstab file this way:

Code:
/dev/sda4   /boot        ext3    defaults,noatime     0 2
/dev/sda2   none         swap    sw                   0 0
/dev/sda4   /            ext3    noatime              0 1

# no cdrom; laptop
# /dev/cdrom  /mnt/cdrom   auto    noauto,user          0 0




Gentoo install #1 has the grub2 bootloader installed and will be updated to catch and find both kernels, hopefully.


Am I way off? Does this seem like the correct way to do this?


Also, I m using initramfs kernel support for both #1 and #2.

bedtime,

Code:
/dev/sda4   /boot        ext3    defaults,noatime     0 2
/dev/sda4   /            ext3    noatime              0 1


Close.

fstab describes complete filesystems and their mount points.
If you do not have a /boot partition, becuase you use the /boot directory on the root filesystem, you do not have a /boot entry in fstab either.

Thanks. I tried this and rebooted in Gentoo #1. I did:

Code:
# grub2-mkconfig -o /boot/grub2/grub.cfg
# mount /boot
# grub2-install /dev/sda


also tried:

Code:
[code]# grub2-mkconfig -o /boot/grub2/grub.cfg
# mount /dev/sda4 /boot
# grub2-install /dev/sda
[/code]


It didn't catch #2 Gentoo. Just #1.

bedtime,

Lets rewind a second ...
When you said you had two installs, I thought you had meant on separate systems.

When you have multiple installs on the same system, they should share /boot, swap and /tmp if tmp is separate.
You don't have to share /boot but it will save your from insanity if you do.

You may have at most one boot loader per drive, ok you can chainload but the start of the chain is your one bootloader.

You must make sure that both your and grub can tell the files apart in the shared /boot but its not an issue as you can name them how you want.
With a shared boot, the entry for boot is identical in both (all) /etc/fstabs

bedtime,

You can always make the menu.config entries manually for your second installation.

Thanks to you both for the answers.

I tried to make an installation with ~x86 and it ended with far too many conflicts, so this mission has been unsuccessful and has been aborted. Reinstalling, wiping drive. I might someday figure this out, but today is not that day. Too complicated and I'm too stupid. So sorry to waste your time and I do appreciate your help.

bedtime,

Stupid is forever and cannot be fixed. You are not that - You installed Gentoo.
It you want to admit to ignorance of Gentoo you are among friends. We were all ignorant of Gentoo at one time.
Ignorance can be fixed with help and encouragement - you will find both here.

We all remember our first steps in Gentoo and the learning process that went with it.

Thanx Neddy and sorry for the negativity. I've got depression and I shouldn't be be contaminating everyone with it.

In any event I've been catching on to the Gentoo way of things so its been getting better.
