/etc/fstab question

[perlsyntax]

after i compile the kernel.I not sure where to put this in my //mnt/gentoo/etc/fsab

real_root=dev/$ROOT

[manzanares]

This line does not normally go in the /etc/fstab
Why do you want to add it?
Or is your question/problem already resolved?

I was just asking the question

[ShinyThings]

if you used genkernel or an initrd on your own, it would be a parameter passed to the kernel. So, it would be like this:

Code: Select all

kernel /boot/vmlinuz root=initrd real_root=/dev/sda3

where /dev/sda3 is the root device. If you dont have an initrd, it should just be root=/dev/sda3

[perlsyntax]

So your saying my genkernel did that all for me then?

Are you confusing fstab with grub's menu.lst/grub.conf ?

[manzanares]

I think 8086 (peculiar name) is asking the correct question. Aren't you mixing up two things?

real_root=dev/$ROOT is a piece of the line in the GRUB.

In the fstab your only reference to ROOT would be (for example)

Code: Select all

#/dev/BOOT      /boot           ext2            noauto,noatime          1 2
#/dev/ROOT      /               ext3            noatime                 0 1
#/dev/SWAP      none            swap            sw                      0 0
#/dev/cdrom     /mnt/cdrom      auto            noauto,ro               0 0

dev/hdb1       /boot           ext2            defaults,noatime        1 2
/dev/hdb3       /               ext3            noatime                 0 1
/dev/hdb2       none            swap            sw                      0 0
/dev/cdrom      /mnt/cdrom      auto            noauto,ro               0 0

Where the secon uncommented bit is my real fstab.
Hence, you repalce

/dev/ROOT for /dev/{where you installed your base system} usually this will be sda3 or hda3, depending.

Code: Select all

dev/hdb1       /boot           ext2            defaults,noatime        1 2

Is there a reason for the lack of /dev in this line? Just curious.

[manzanares]

Very sharp! You are right: should be:

Code: Select all

/dev/hdb1

Just an edit error. Thank you.

I just did the genkernel and if i am right i need to make a /boot/grub.conf file and i not sure how one will look like.

[NathanZachary]

There are examples of /boot/grub/grub.conf in the handbook (one for genkernel and one for non-genkernel):

http://www.gentoo.org/doc/en/handbook/h ... #doc_chap2

Hope that helps.

Are you allergic to the gentoo installation handbook?

[perlsyntax]

yes i am
