[Bug 1030772] Re: btrf file system was selected as root partitions (Live USB). produce the same bug report as Live DVD installation

[aimwin]

From
https://help.ubuntu.com/community/btrfs
............... You must install it to either the parent (sda rather than sda1; MBR/Reserved Sectors) 'OR' use a dedicated /boot partition as described in the forum post below. 
When installing Ubuntu in one large btrfs-Partition without an extra boot-partition, take care to keep about 1 Mib space free at the beginning of the disk. When there is not this space, the installer fails at the end when trying to install Grub! ............

And 
https://btrfs.wiki.kernel.org/index.php/Ubuntu_support
......long and involve good understanding of btrf. and how to........
That is not an easy normal installation of ext4... I just learn that today after reading many more info on how to btrf?

Can someone confirm the above issue.

That I am too naive to just select the btrf in replacement of ext4,
during the normal installation.

Because if we want to use btrf we need to follow these instructions in 
https://btrfs.wiki.kernel.org/index.php/Ubuntu_support

or it is another bug in the 12.04.1 installation programs?

Title:
  btrf file system was selected as root partitions (Live USB). produce
  the same bug report as Live DVD installation

Status in “grub-installer” package in Ubuntu:
  New

Bug description:
  This is second time identical Grub installation EROR and termination
  of installation.

  Both with Live DVD, which I report in about 1 hour ago.
  This time I use Live USB, complete clean booted in to Desktop with no error.

  Then I execute installation and choose btrf file system as root
  partition or install partition.

  I think it is the btrf option that crash the installation.

  Since I have reinstall (using Live DVD 12.04.1) to sda12 with ext4
  with 100% perfect, test boot into new hard disk installation.

  I will reinstall with Live USB with ext4 installation, and report
  back.
