Hi Andre, Nice to see you here again. I notice that your tutorial thread at the Ubuntu Forums is attracting many readers :-)
Yes I know there are advantages with ext partitions and how to tweak them for optimal performance and lifetime on a pendrive, but I didn't want to make the setup too complicated. You may be right, that there are enough advantages with ext filesystems, so that I should store the isofiles there (and have only a small fat32 partition to allow for UEFI booting). Anyway, pendrives are often slow, and I have found that rsync behaves much better than zsync, when the target drive for updating is a pendrive. I think this is true also with ext filesystems. One big advantage is that there is no need for copying/cloning/flashing from the internal drive to the pendrive. The slowness of the internet connection matches quite well the slowness of a USB 2 connection, so you don't lose much time anyway. Fragmentation is another reason to avoid fat 32. I guess I have to watch out for that, but as long as the iso files remain about the same size and the file system is far from full, that should be a small problem in this case. I'm thinking about the casper-rw partition. Could it be used for the iso files in a convenient way? Maybe - and it is better to have few partitions, when the drive is small.
