[Bug 1309332] Re: Installer crash on un(pre)formatted btrsf root install

[Jay Aurabind]

bump! :)

** Description changed:

  My chosen root parition is a btrfs, which is has been formatted
  previously. Many other distros live in that partition under different
  subvolumes. Prior to installation, I created a fresh subvolume "ubuntu"
  and made it the default so that when the installer mounts the BTRFS
  partition, it sees a fresh space. Two cases crashed:
  
  1) BTRFS root, with separate ext4 /boot and bootloader installation to
  my Flash drive (sdb) (beacuse I dont want the installer to touch my
  existing grub config, which is managed by other fellow distros.
  
  2) BTRFS root, without separate ext4 boot partition, and bootloader
  installation to the BTRFS root.
  
  My /var/log/syslog: http://pastebin.com/80FR04sv
  
+ My /var/log/partman: http://pastebin.com/WrZSsseH
  
- My /var/log/partman: http://pastebin.com/WrZSsseH
+ Sorry I missed an important thing: The real reason for crash appears to
+ be because I chose *NOT TO FORMAT* root or boot partitions. Installation
+ was successful when I chose *YES* to format (ext4 root), but didnt try
+ out with BTRFS root as I couldnt risk the a data loss due to the format
+ operation.
