It is easy: aufs and unionfs needs a writable filesystem to use for "cow" (copy on write), the default debian-live boot mounts a tmpfs to provide that. If "persistent" is a boot time parameter the script will try to find a file or a partition named (labeled) "live-rw" and if it finds it it tries to mount it instead of the tmpfs, so your modification will survive reboots. This solution is expensive for a usb-key, although is fine for a mounted hd partition or a file image. Since it was expensive for usb using, it rose the needings for a faster system like my snapshot solution. This solution should work right now, but live-snapshot could not help you in building the file-image at runtime since "live/cow" is hidden 'cause of a mount option bug. > > Any wishlist or ideas on snapshot/persistent topic here? > > I've been using ext3 since ext2 corrupt too easily. ext2/ext3 are both supported now. -- ESC:wq -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. _______________________________________________ debian-live-devel mailing list debian-live-devel@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/debian-live-devel
