I knew there is going to be confusion with http://ccache.samba.org/ which has _nothing_ to do with this project. I am now going to rename this project to "compcache" to avoid any confusion. New project home will be: http://code.google.com/p/compcache/ It will take few days for this transition to complete. > FYI, ccache still seems solid under Hardy. > A 128MB ccache swap allowed me to easily install from the liveCD on a > VM with only 192MB of ram, rather than the 384MB officially required > for Gutsy. > However I found a funny bug in ubiquity: > https://bugs.launchpad.net/bugs/193267 > http://www.ucc.asn.au/~mccabedj/ccache/Screenshot-Hardy-fdccache.png > Installing Hardy to /dev/ccache sound like a great idea ;) Yeah. Interesting :) - /dev/ccache really should not be visible there since its _not_ possible to install on this device! This is not a _generic_ block device and can be used only as a swap disk. However, I am not sure how to make it invisible to installer (maybe load module after partitioning step is over?). > > I am using a DualCore, with the iso sitting on the harddisk, so a real > low-mem machine could be a lot slower. however Ubuntu is meant to > require 384MB of memory to install and 256MB of memory to use.
