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)? -- Tomasz Chmielewski http://wpkg.org
