FYI - I've been using btrfs with 2.6.31.1 kernel for a few days as a
rootfs on a small mips system (ASUS WL-500gP - 32 MB RAM, 266 MHz CPU).
btrfs filesystem is placed on a USB-stick connected to the device
(internal flash only contains the kernel).
My main motivation for using btrfs on this small system was compression
this filesystem offers - flash storage is still prohibitively expensive
when compared to traditional hard disks (i.e. 32 GB USB-stick costs as
much as a 1 TB HDD).
So far, everything looks fine, although I didn't try to stress it much
(or use snapshots and/or make the filesystem full).
Certainly one thing I'm missing in btrfs is the ability to use swapfiles
- is it planned one day (or perhaps some serious surgery in MM would be
needed first)?
