Oh no. I just found out about unionfs very recently, thanks to solar. |

The current implementation is completely manual (and asynchronous) : the |
16 |
contents of the partition is overlaid over the live filesystem at boot, |
17 |
and you can remount the partition later on to save modified files. The |
18 |
idea is to backup some /etc and /var things that you want to keep over a |
19 |
reboot. |

What is GNAP-specific, though, is the idea to add a tarball to a LiveCD |
22 |
and have an init script overlay files over the filesystem at boot. This |
23 |
allows user-level customization of the LiveCD configuration files in |
24 |
seconds. The "R/W overlay" feature is just there to avoid burning a new |
25 |
LiveCD whenever you change a conf file. |
