I just found out about unionfs very recently, thanks to solar. The current implementation is completely manual (and asynchronous) : the contents of the partition is overlaid over the live filesystem at boot, and you can remount the partition later on to save modified files. The idea is to backup some /etc and /var things that you want to keep over a reboot. What is GNAP-specific, though, is the idea to add a tarball to a LiveCD and have an init script overlay files over the filesystem at boot. This allows user-level customization of the LiveCD configuration files in seconds. The "R/W overlay" feature is just there to avoid burning a new LiveCD whenever you change a conf file. -- Koon -- gentoo-dev@gentoo.org mailing list
