well, I will make a good try to add btrfs support to android kernel! I will start with siyah kernel for galaxy s2, I'm a kernel newbie, so any help is greatly appreciated! (I will also try to reformat some system partitions to btrfs...) trying to figure out the partition table of the android... sorry for being off-topic!

I've no idea on how btrfs performs with a flash disk actually. My btrfs partition just locates on a normal hdd so I have never thought about it :-)

is it actually safe to format an usb flash to btrfs? won't it destroy the flash because of the read/writes? On Jul 31, 2012 2:20 AM, "Zhengyu Xu" <xzy3186@gmail.com> wrote:
Trying to install Arch on a USB key, I am having trouble getting a bootable system. I created a basic BTRFS filesystem and mounted it with SSD optimizations and compression. I didn't create any subvolumes or anything else that is said to be problematic when booting to a BTRFS filesystem. From that point, I followed the installation guide for a normal install. However, after reading the documentation for GRUB and Syslinux, my newly created install doesn't boot. I looked at the wiki entry for installing to a USB key, but it is still written for AIF and grub-legacy. However, the

visually impaired and use speech to install and use Arch, I am unable to see whether I am in a "normal shell" or a rescue shell, or even what kind of issue the bootloaders are having that keeps them from finding a kernel. Should I be using a different filesystem other than BTRFS, even though both bootloaders are said to support it? Should I not be using compression on my filesystem? Could this be a problem that is entirely unrelated to the filesystem I'm using? Any help is greatly appreciated. ~Kyle
Did you add usb and btrfs to the hooks array in your mkinitcpio.conf?
