Just one technical remark about number of images handled. I haven't tried the cloops, but for ordinary loop the busybox version used seems to be limited in number. Has anybody tried how many will actually be mounted of KNOPPIX..KNOPPIX9? All, as we should hope for, or less?

BTW, I wonder how a subversion repo would work for persistent store backup with the modest amount of data/files we have there after remastering. I think about trying it myself, but if anybody already has, it would be interesting to hear about the experiences. The rationale is that it is inefficient to back up the image file often when the actual changes made are only to a limited number of files.
