Bootchart forks also a program that collects process informations: acct. This can't hold its data in memory and write them later. This is out of reach for bootchart. Currently bootchart do not support holding data in memory, but I can talk to upstream about this issue. Regardless of this, I need a writable filesystem for acct.
