Dear list, especially Greg and Mickey, I've updated the working copy of the CCD Mirroring HOWTO. In particular, I've split off the comparison to software RAID into a separate section and clarified that ccd does not do automatic recovery, and I've rewritten the section on labeling to state that the c partition must be set to unused, and normal partitions created instead.
Please take a look at http://morgenes.shire.sytes.net/~inglorion/documents/tutorials/ccd/ and let me know what you think about the new wording. Bob --- The only thing you know for sure is that you never know anything for sure.
