They have about 3.1GB used, though I never bothered to uninstall anything. It's likely that an install of the server version of 6.06LTS would be a better way to start, then add the EMC2 repositories and install.

The PartImage compressed image was ~900MB. I did it as a partition image, rather than a full disk, but it supports either. It's a lot like Ghost, if you're familiar with that. I'm not sure how well flash will work as swap. Although the technology has kept improving, there are still write cycle limits for flash drives. > Chances are, you could probably do the same thing on a 2GB USB Flash > Drive if your motherboard supports USB Flash Boot (most modern ones > do).

Though there has been lots of talk about headless EMC2 computers running the machine, using another PC for the GUI. This is what my application was for - the embedded machine has no display/keyboard, if you need to communicate with it, you plug in an ethernet cable and use ssh. I have some fairly minimalist runscripts to make runlevel 2 perform better for RT. I'll post them on the wiki when I have a chance. If you can, please either create a wiki page with your information, or if there's already a page that covers embedding EMC on a flash drive, please update it.
