I believe I should stick to ext2, right? If you mean compared to jffs2 then probably yes, better to stick with ext2. If you mean is ext2 the best choice over anything else... well that's an open question (or so I'm told). You would need to ask a filesystem expert really but it apparently depends on the workload, the characteristics of the "disks" and whether you need journaling. -- Sitsofe | http://sucs.org/~sits/
