That card should have ca 20MB/s r&w, I think that's fine. I would say just go ahead and try - only beware that if the PC identifies it as an mmcblk device with the built-in reader, you have to either use an external card reader, or modify minirt.gz something in the way of marlas' method, http://www.knoppix.net/forum/threads...mmcblk0-device

As regards the handling of knoppix-data.img, if you don't have soething special rewritable to keep, you might just let Knoppix create a new one. The main reasons I recreate it upon remastering, is to keep my modified /home outside of the remastered image (I might give it to someone), to save space in the new cloop by purging package data that will be rewritten anyway, and to save one step at the first booting of the new version.

Squashfs vs cloop is really no big deal in our context. Squashfs image is smaller than the quick-compressed cloop, and takes one less step to create. But when we have enough space on our USB devices, and use scripts, that's not very significant. Klaus K clearly has his reasons for sticking with cloop, but I still haven't got exactly what is most important, with the present versions. I have been using about half and half of them, often not knowing which variety I'm running right now - and that's just the way I like it. I might go for more exclusive squashfs, though. It's just that I then have to modify the minirt, which I also try to avoid as much as posssible.
