[15:08]  * cwillu_at_work has successfully booted a btrfs root on a beagleboard with rootstock
[15:09] <cwillu_at_work> I'm tempted to suggest it has a default rootfs, as it doesn't have the issues that ext3/4 has on sd cards re: journalling, nor the issues that ext2 has with the lack of journalling/consistency
[15:12] <Martyn> I've managed to put together a ubi/ubifs as well... but that means you need direct access to the MTD to do UBI
[15:12] <Martyn> Any issues on getting a btrfs root working that you found?
[15:13] <cwillu_at_work> not really
[15:13] <cwillu_at_work> uou need a kernel with the appropriate modules compiled in, or available in an initramfs, although rcn's kernel packages have it enabled for a month or so now
[15:14] <cwillu_at_work> the ssd optimizations are supposed to be automically enabled if it detects non-rotating media, although I just err on the side of caution and put "btrfs.ssd" on the kernel boot line
[15:14] <cwillu_at_work> I've been using it on a server for a while now, and also just started using it on my laptop, mainly to flush out these sorts of issues
[15:15] <cwillu_at_work> update-grub doesn't get along with it very well, but that's not really an issue with arm
[15:16] <cwillu_at_work> an amusing trick would be to hotswap rootfs devices:  boot off the sd card, plug in a usb reader with another card, add the new card to the btrfs root, and then remove the original card :)
[15:17] <cwillu_at_work> for those uptime critical embedded installations where the sd is starting to give write errors, but you can't afford to reboot \o/
