Some say = it's THE=20 way to use CF cards, others say it's totally useless since CF cards = have=20 their own wear leveling system build in.=20 There were reports that it takes forever to mount a cf card with = blkmtd/jffs2.=20 I've tried it, it does take a long time for the whole cf, but in = smaller=20 partitions (2 - 3 M) it's acceptable.=20 questions:=20 * So, is it wise, to use a setup like that in a system, let's say to = update=20 system configuration files on a small , sepate partition ?=20 * Are there some parameters that I can give to blkmtd.o to speed up the = process of mounting?
