[Bug 879109] Re: Grub install failed on sda and sda3-btrfs

[Caio Costa]

I've tried to install Xubuntu 12.04 on a 16 GB thumb drive, following partition table
1st partition: Primary, NTFS, 8GB
2nd partition: Primary, ext2, /boot, 0.5GB
3rd partition: Primary, brtfs, /, 7.5GB

And then I've hit the grub-install error:

ubuntu grub-installer: cannot read `/grub/core.img' correctly

For those also looking to install ubuntu on a thumb drive, I've found
that ext4 with " journal-data-writeback" option set on tune2fs, and
mount options "commit=120,data=writeback,noatime"  added to /etc/fstab
offer acceptable performance.
