casper is not installed on the target system during the installation process and afaict usb-creator doesn't require capser or lupin-casper so I'm really not sure what happened to your system.
Additionally, compcache (according to the casper changelog) should only be used on systems (running casper) with less than 512MB of ram. casper (1.232) lucid; urgency=low * bump compcache size to 50% on live images for machines with less than 512MiB. This makes sure we don't hit OOM errors on systems with only 256MiB of RAM. -- Oliver Grawert <o...@ubuntu.com> Mon, 12 Apr 2010 08:10:06 +0200 ** Changed in: casper (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/933712 Title: casper configures system to use 50% ram for compressed swap post installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/933712/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
