Suppose I want to boot DSL from usb stick on a thinclient (no cdrom, no hda).
Is it <necessary|possible|advantageous> to format the usb pen with two ext2 partitions (one for the image and one for /home, /opt)? Or does DSL <needs|assumes> vfat?

By the way, on my normal pc, I get the message that umount KNOPPIX fails and I should try cloop instead. What's that about? In which file can I change this?

Also, is it possible to change the font size in xterm (apart from changing the resolution)?

For the usb stick it is not always necessary to have 2 partitions, it just makes it easier to actually change the system and keep your files when you decide to format or update the system. Ext2 is good for if you want to use only linux although what I have for example is a usb drive formatted with vfat which is where I install the bootloader and then where I can place documents so they are readable in windows as well. the other partition I have as ext2, although if you want you can just format the whole thing and use it as a whole. No probs there. They claim that ext2 is supposed to make the drive last longer because it writes less than ext3... I am not sure how valid that point is about longetivity of the drive but it seems to popular believe. For the other two questions I have no idea what that is about although I suppose you can try and edit your fstab file of how knoppix is mounted

Thanks for your answer! I only use linux, so I'll make two ext2 partitions. Ext3 is Ext2+journaling, there's also jffs (Journaling Flash File System) but I'm not sure it's part of DSL (maybe it should be).
