[gentoo-user] cloning problem

[gentoo-user] cloning problem

[Helmut Jarausch]

Hi,

since not too long I have a problem when cloning a Gentoo system
on to a machine with identical hardware.
I copy / /usr and /LOCAL to the new machine, edit several files in /etc
rebuilt the kernel and reinstall grub:0. Furthermore I have adapted the
fstab file in the initramfs.

On the very first boot the cloned system fails to mount all file systems
even /dev/pts which is a bit problematic when doing all this from  
remote.

I get PTY allocation request failed on channel 0

Luckily I still can use the console on the remote system although I  
don't
get a prompt.

Just doing
mount -a

and rebooting seems to fix the problem.

Still, I'm interested what's going there?

Many thanks for a hint,
Helmut.

Did you copy /dev/null and /dev/console to the new machine. These need to
exist on the root partition as they are needed before udev starts.

Thanks Neil,
what do you mean by copy?

When cloning, I transfer a tarball of the root and usr partition.
Doesn't that suffice?

The only thing which comes to my mind now is that the tarball was  
created from
a live root partition.

Helmut.

There's the problem. The live root partition has a devfs mounted on /dev
so the contents of /dev on the root filesystem are unavailable. Either
use a live CD or bind mount / somewhere and copy that.

mount --bind / /mnt/tmp
cd /mnt/tmp
tar -czf tarball.tgz .
